ValuesManager (Smart GWT EE API 5.0p (2021-05-26))

java.lang.Object
- com.smartgwt.client.core.BaseClass
- - com.smartgwt.client.widgets.form.ValuesManager

All Implemented Interfaces:

com.google.gwt.event.shared.HasHandlers, HasHiddenValidationErrorsHandlers
```
public class ValuesManager
extends BaseClass
implements HasHiddenValidationErrorsHandlers
```
The ValuesManager manages data from multiple member forms.
If a single logical form needs to be separated into multiple DynamicForm instances for Layout purposes (for example, spanning one logical form across multiple Tabs), a ValuesManager can be used to make the forms act as one logical form, supporting all value-related APIs otherwise called on DynamicForm directly.
A ValuesManager has no visual representation - it is strictly a logical entity, and the member forms provide the user interface. You can initialize a ValuesManager with a set of member forms (by setting members at init) or add and remove member forms dynamically.
Calling ValuesManager.setValues() on a ValuesManager will automatically route new field values to whichever member form is showing an editor for that field. Likewise, calling ValuesManager.validate() will validate all member forms, and ValuesManager.saveData() will initiate a save operation which aggregates values from all member forms.
Like a DynamicForm, a ValuesManager can be databound by setting dataSource. In this case all member forms must also be bound to the same DataSource.
In general, when working with a ValuesManager and its member forms, call APIs on the ValuesManager whenever you are dealing with values that span multiple forms, and only call APIs on member forms that are specific to that form or its fields.
Note that, just as a DynamicForm can track values that are not shown in any FormItem, a ValuesManager may track values for which there is no FormItem in any member form. However, when using a ValuesManager these extra values are only allowed on the ValuesManager itself. Member forms will not track values for which they do not have FormItems.

  - setDisableValidation
```
public void setDisableValidation(java.lang.Boolean disableValidation)
```
    If set to true, client-side validators will not run on the form when validate() is called. Server-side validators (if any) will still run on attempted save.
    Note : This is an advanced setting
    
    Parameters:
    disableValidation - Default value is null

```
public void setRemoveOperation(java.lang.String removeOperation)
```
    operationId to use when performing remove operations.
    
    Parameters:

    See Also:
    Operations overview and related methods
  - getRemoveOperation
```
public java.lang.String getRemoveOperation()
```
    operationId to use when performing remove operations.
    
    Returns:
    String
    See Also:
    Operations overview and related methods
  - setSaveOperationType
```
public void setSaveOperationType(DSOperationType saveOperationType)
```
    Default DSOperationType to be performed when DynamicForm.saveData() is called. This property is automatically set on a call to DynamicForm.editRecord() or DynamicForm.editNewRecord(), or may be set directly via DynamicForm.setSaveOperationType().
    If saveOperationType is unset, the form will heuristically determine whether an "add" or "update" operation is intended based on whether the primaryKey field is present and editable.
    
    If this method is called after the component has been drawn/initialized: Setter for the default DSOperationType when DynamicForm.saveData() is called. Note that this property can also be set by calling DynamicForm.editRecord() or DynamicForm.editNewRecord()
    
    Parameters:
    saveOperationType - Operation type to use as a default. Valid values are "add" or "update".. Default value is null
  - getSaveOperationType
```
public DSOperationType getSaveOperationType()
```
    Default DSOperationType to be performed when DynamicForm.saveData() is called. This property is automatically set on a call to DynamicForm.editRecord() or DynamicForm.editNewRecord(), or may be set directly via DynamicForm.setSaveOperationType().
    If saveOperationType is unset, the form will heuristically determine whether an "add" or "update" operation is intended based on whether the primaryKey field is present and editable.
    
    Returns:
    Returns the DSOperationType to be performed when DynamicForm.saveData() is called. Valid options are "add" or "update".
    If a DSRequest configuration object is passed in containing an explicit operationType this will be returned. Otherwise saveOperationType will be returned. This attribute is automatically set via calls to data binding methods such as DynamicForm.editNewRecord(), or it may be set explicitly.
    If no explicit saveOperationType is specified for this form, the system will look at the current values for the form. If the form has no value for the primaryKey field, or that field is editable and has been modified we assume an add operation, otherwise an update. If the form is a member of a ValuesManager, the primary key field value will be derived from the valuesManager's values object.
  - setSuppressValidationErrorCallback
```
public void setSuppressValidationErrorCallback(java.lang.Boolean suppressValidationErrorCallback)
```
    When calling ValuesManager.saveData() on a form or valuesManager, by default if the server returns an error code, any callback passed into saveData() will not be fired. If the error code returned by the server indicates a validation error, it will be displayed to the user by updating the form items to show the error messages, and firing any specified hiddenValidationErrors handler, otherwise the standard RPCManager error handling logic would be invoked.
    Developers who want to handle errors themselves can override this default by specifying dsRequest.willHandleError on the DSRequest. In this case the callback passed in will be fired even if the server returns an error status code.
    If suppressValidationErrorCallback is set to true, if a save attempt returns a validation error code, the user-specified callback will not be fired even if willHandleError:true was specified on the dsRequest - though for other error codes, the callback would be fired if willHandleError is specified on the request. Note that this is the historical behavior for SmartGWT builds 4.0 and earlier
    Note : This is an advanced setting
    
    Parameters:
    suppressValidationErrorCallback - Default value is false
  - getSuppressValidationErrorCallback
```

  - setUpdateOperation
```
public void setUpdateOperation(java.lang.String updateOperation)
```
    operationId to use when performing update operations.

    See Also:
    Operations overview and related methods

    Returns:
    String
    See Also:
    Operations overview and related methods
  - addMember
```
public void addMember(DynamicForm member)
```
    Add a new member to this valuesManager. Any Canvas can be a member of a valuesManager, even components like Layout or TabSet that do not actually have any values to manage. When "valueless" components like these bind to a ValuesManager, it is in order to provide their own child components with a shared valuesManager so that complex data can be displayed and edited - see DataPath for more details.
    For components like DynamicForm and ListGrid, which do have a set of values to manage, the component's values will subsequently be available through this valuesManager.
    Note on pre-existent values when the member component is a DynamicForm:
    If the valuesManager has a value specified for some field, for which the member form has an item, this value will be applied to the member form. This is true whether the item has a value or not.
    However if the member form has a value for some field, and the ValuesManager does not have a specified value for the same field, we allow the valuesManager to pick up the value from the member form.
    
    Parameters:
    member - component (or ID of component) to add to this valuesManager as a member.

  - cancel
```
public void cancel()
```
    This method exists for clean integration with existing server frameworks that have a 'cancel' feature which typically clears session state associated with the form. When this method is called, an RPC is sent to the server with a parameter named cancelParamName with the value cancelParamValue.
    Note that no other form data is sent. By default the current top-level page is replaced with the reply. If you wish to ignore the server reply instead, call this method like this:
```
  dynamicFormInstance.cancel({ignoreTimeout: true, target: null});
  
```

    Parameters:
    criteria - search criteria
    callback - callback to invoke on completion
    requestProperties - additional properties to set on the DSRequest that will be issued

  - getChangedValues
```
public java.util.Map getChangedValues()
```
    Returns all values within this DynamicForm that have changed since DynamicForm.rememberValues() last ran. Note that DynamicForm.rememberValues() runs on dynamicForm initialization, and with every call to DynamicForm.setValues() so this will typically contain all values the user has explicitly edited since then.
    
    Returns:
    changed values in the form
    See Also:
    getOldValues()
  - getErrors
```
public java.util.Map getErrors()
```
    Returns the set of errors for this valuesManager. Errors will be returned as an object of the format
    {field1:errors, field2:errors}
    Where each errors object is either a single error message or an array of error message strings.
    
    Returns:
    Object containing mapping from field names to error strings. Returns null if there are no errors for this valuesManager.
    See Also:
    Errors overview and related methods
  - getMemberForField
```
public Canvas getMemberForField(java.lang.String fieldName)
```
    Given a fieldName or dataPath, this method will find the member responsible for interacting with that field's value. If no form is found, returns null.
    
    Parameters:
    fieldName - fieldName or dataPath to check
    
    Returns:
    member responsible for displaying this field (may be null).
  - getOldValues
```
public java.util.Map getOldValues()
```
    Returns the set of values last stored by DynamicForm.rememberValues(). Note that rememberValues() is called automatically by DynamicForm.setValues(), and on form initialization, so this typically contains all values as they were before the user edited them.
    
    Returns:
    old values in the form
    See Also:
    getChangedValues()
  - getValues
```
public java.util.Map getValues()
```
    Returns the current set of values for the values manager instance. This includes the values from any form managed by this manager, as well as any values explicitly applied via ValuesManager.setValues().
    
    Returns:
    a map of the values for this manager
  - addHiddenValidationErrorsHandler
```
public com.google.gwt.event.shared.HandlerRegistration addHiddenValidationErrorsHandler(HiddenValidationErrorsHandler handler)
```
    Add a hiddenValidationErrors handler.
    Method to display validation error messages for a valuesManager when there is not currently visible form item displaying the errors. This will be called when validation fails for
    - a field in a hidden or undrawn member form
    - a hidden field in a visible member form
    - for databound ValuesManagers, a datasource field with specified validators, but not associated item in any member.
    Implement this to provide custom validation error handling for these fields.
    By default hidden validation errors will be logged as warnings in the developerConsole. Call HiddenValidationErrorsEvent.cancel() from within HiddenValidationErrorsHandler.onHiddenValidationErrors(com.smartgwt.client.widgets.form.events.HiddenValidationErrorsEvent) from this method to suppress that behavior.
    
    Specified by:
    
    addHiddenValidationErrorsHandler in interface HasHiddenValidationErrorsHandlers
    
    Parameters:
    handler - the hiddenValidationErrors handler
    
    Returns:
    HandlerRegistration used to remove this handler
  - hasErrors
```
public java.lang.Boolean hasErrors()
```
    Are there any errors associated with any fields in this valuesManager?
    
    Returns:
    returns true if there are any outstanding validation errors, false otherwise.
    See Also:
    Errors overview and related methods
  - hasFieldErrors
```
public java.lang.Boolean hasFieldErrors(java.lang.String fieldName)
```
    Are there any errors associated with a field in this valuesManager?
    
    Parameters:
    fieldName - field to check for errors
    
    Returns:
    returns true if there are any outstanding validation errors, false otherwise.
    See Also:
    Errors overview and related methods
  - isNewRecord
```
public java.lang.Boolean isNewRecord()
```
    Returns true if saveOperationType is currently "add". See saveOperationType.
    
    Returns:
    whether this form will use an "add" operation when saving
  - removeMember
```
public void removeMember(DynamicForm member)
```
    Remove a member form from this valuesManager, so its values are no longer managed by this instance. This does not clear the values associated with the form from the valuesManager - they will still be available via valuesManager.getValues(), but will not be updated as the form is manipulated.
    
    Parameters:
    member - form (or ID of form) to remove from this valuesManager
    See Also:
    removeMembers(com.smartgwt.client.widgets.form.DynamicForm...)
  - removeMembers
```
public void removeMembers(DynamicForm... members)
```
    Remove multiple member forms from this valuesManager.
    
    Parameters:
    members - array of forms to remove
    See Also:
    removeMember(com.smartgwt.client.widgets.form.DynamicForm)
  - resetValues
```
public void resetValues()
```
    Same as DynamicForm.reset().
  - saveData
```
public void saveData()
```
    Validate and then save the form's current values to the DataSource this form is bound to.
    If client-side validators are defined, they are executed first, and if any errors are found the save is aborted and the form will show the errors.
    If client-side validation passes, a DSRequest will be sent, exactly as though DataSource.addData() or DataSource.updateData() had been called with ${isc.DocUtils.linkForRef('method:DynamicForm.getValues','the form\'s values')} as data. The operationType will be either "update" or "add", depending on the current saveOperationType.
    On either a client-side or server-side validation failure, validation errors will be displayed in the form. Visible items within a DynamicForm will be redrawn to display errors. Validation failure occurring on hidden items, or DataSource fields with no associated form items may be handled via DynamicForm.hiddenValidationErrors() or ValuesManager.hiddenValidationErrors().
    In the case of a validation error, the callback will not be called by default since the form has already handled the failed save by displaying the validation errors to the user. If you need to do something additional in this case, you can set willHandleError via the requestProperties parameter to force your callback to be invoked. However, first consider:
    - if you are trying to customize display of validation errors, there are several built-in modes and DynamicForm.showErrors() may be a better place to put customizations.
    - for unrecoverable general errors (eg server is down), central error handling in invoked, so consider placing customizations there unless an unrecoverable error should be handled specially by this specific form.

    Validate and then save the form's current values to the DataSource this form is bound to.
    If client-side validators are defined, they are executed first, and if any errors are found the save is aborted and the form will show the errors.

    DataBoundComponentMethods overview and related methods, Add Example
  - setValues
```
public void setValues(java.util.Map values)
```
    Replaces the current values of the ValuesManager and all member components with the values passed in.
    Values should be provided as an Object containing the new values as properties, where each propertyName is the name of a form item in one of the member forms, and each property value is the value to apply to that form item via FormItem.setValue().
    Values with no corresponding form item may also be passed, will be tracked by the valuesManager and returned by subsequent calls to ValuesManager.getValues().
    Any FormItem for which a value is not provided will revert to its defaultValue. To cause all FormItems to revert to default values, pass null.
    This method also calls ValuesManager.rememberValues() so that a subsequent later call to ValuesManager.resetValues() will revert to the passed values.
    
    Parameters:
    values - new set of values for this values manager.
  - showFieldErrors
```
public void showFieldErrors()
```
    Method to explicitly show the latest set of validation errors present on some field within this ValuesManager.
    If the field in question is present as a visible item in a member form, the form item will be redrawn to display the error message(s). Otherwise ValuesManager.hiddenValidationErrors() will be fired to allow custom handling of hidden errors.
    
    See Also:
    Errors overview and related methods
  - submit
```
public void submit()
```
    submit() is automatically called when a SubmitItem in a member form is clicked, or if saveOnEnter is set for some member form, when the "Enter" key is pressed in a text input. Submit can also be manually called.
    If valuesManager.submitValues() exists, it will be called, and no further action will be taken.
    Otherwise, ValuesManager.saveData() will be called to handle saving via Smart GWT databinding.
    The parameters to submit() apply only if submit() will be calling ValuesManager.saveData(). If you override submit(), you can safely ignore the parameters as Smart GWT framework code does not pass them.
    
    See Also:
    com.smartgwt.client.widgets.form.ValuesManager#submitValues, DataBoundComponentMethods overview and related methods
  - submit
```
public void submit(DSCallback callback)
```
    See Also:
    submit()
  - submit
```
public void submit(DSCallback callback,
          DSRequest requestProperties)
```
    submit() is automatically called when a SubmitItem in a member form is clicked, or if saveOnEnter is set for some member form, when the "Enter" key is pressed in a text input. Submit can also be manually called.
    If valuesManager.submitValues() exists, it will be called, and no further action will be taken.
    Otherwise, ValuesManager.saveData() will be called to handle saving via Smart GWT databinding.
    The parameters to submit() apply only if submit() will be calling ValuesManager.saveData(). If you override submit(), you can safely ignore the parameters as Smart GWT framework code does not pass them.
    
    Parameters:
    callback - callback to invoke on completion.
    requestProperties - additional properties to set on the DSRequest that will be issued
    See Also:
    com.smartgwt.client.widgets.form.ValuesManager#submitValues, DataBoundComponentMethods overview and related methods
  - synchronizeMembers
```
public void synchronizeMembers()
```
    Update all of this ValuesManager's members to reflect the current values held by the ValuesManager. It is not normally necesary to manually synchronize members, but you will need to do so if you switch off automatic synchronization.
  - validate
```
public java.lang.Boolean validate()
```
    Validate the current set of values for this values manager against validators defined in the member forms. For databound valuesManagers, also perform validation against any validators defined on datasource fields.
    Note that if validation errors occur for a value that is not shown in any member forms, those errors will cause a warning and ValuesManager.hiddenValidationErrors() will be called. This can occur if:
    - A datasource field has no corresponding item in any member form
    - The item in question is hidden
    - The member form containing the item is hidden.
    
    Returns:
    true if all validation passed
    See Also:
    Splitting Example
  - valuesHaveChanged
```
public java.lang.Boolean valuesHaveChanged()
```
    Compares the current set of values with the values stored by the call to the DynamicForm.rememberValues() method. rememberValues() runs when the form is initialized and on every call to DynamicForm.setValues(). Returns true if the values have changed, and false otherwise.
    
    Returns:
    true if current values do not match remembered values
    See Also:
    getChangedValues(), getOldValues()
  - getById
```
public static ValuesManager getById(java.lang.String ID)
```
    Retrieve a ValuesManager by it's global ID.
    
    Parameters:
    ID - global ID of the ValuesManager
    
    Returns:
    the ValuesManager, or null if not found
  - onInit
```
protected void onInit()
```
    Overrides:
    
    onInit in class BaseClass
  - onInit_ValuesManager
```
protected void onInit_ValuesManager()
```
  - showErrors
```
public void showErrors()
```
    If this form has any outstanding validation errors, show them now.
    This method is called when the set of errors are changed by DynamicForm.setErrors(java.util.Map, boolean) or DynamicForm.validate(boolean).
    Default implementation will redraw the form to display error messages and call com.smartgwt.client.widgets.form.DynamicForm#handleHiddenValidationErrors to display errors with no visible field.
    
    Note: This is an override point. This method may be overridden to perform custom display of validation errors.
  - setDataSource

  - getMembers
```
public DynamicForm[] getMembers()
```
    Returns an array of members in this ValuesManager. Note that this is a convenience method: it returns an array of DynamicForm, and so can only be validly used if all the ValuesManager's members are DynamicForms (a ValuesManager's members are traditionally DynamicForms, but they can be any kind of Canvas). See getMemberCanvases()
    
    Returns:
    the members
  - getMemberCanvases

    the members
  - removeMember
```
public void removeMember(java.lang.String formID)
```
    Remove a member form from this valuesManager, so its values are no longer managed by this instance. This does not clear the values associated with the form from the valuesManager - they will still be available via valuesManager.getValues(), but will not be updated as the form is manipulated.
    
    Parameters:
    formID - ID of the form to remove from this valuesManager
  - rememberValues
```
public com.google.gwt.core.client.JavaScriptObject rememberValues()
```
    Make a snapshot of the current set of values, so we can reset to them later. Creates a new object, then adds all non-method properties of values to the new object. Use resetValues() to revert to these values. Note that this method is automatically called when the values for this form are set programmatically via a call to DynamicForm.setValues().
    
    Returns:
    copy of current form values
  - setErrors
```
public void setErrors(java.util.Map errors,
             boolean showErrors)
```
    Setter for validation errors on this form. Errors passed in should be a Map in the format {fieldName1:errors, fieldName2:errors}
    Where the errors value may be either a string (single error message) or an array of strings (if multiple errors should be applied to the field in question).
    
    Parameters:
    errors - list of errors as a map with the field names as keys
    showErrors - If true redraw form to display errors now. Otherwise errors can be displayed by calling showErrors() Note: When the errors are shown, handleHiddenValidationErrors() will be fired for errors on hidden fields, or with no associated formItem.
  - setFieldErrors
```
public void setFieldErrors(java.lang.String fieldName,
                  java.lang.String error,
                  boolean showErrors)
```
    Set field validation error for some field. The showErrors parameter allows the errors to be displayed immediately. Alternatively, an explicit call to DynamicForm.showFieldErrors(java.lang.String) will display the errors for this field.
    
    Parameters:
    fieldName - field to apply the new errors to
    error - error to apply to the field in question
    showErrors - If true this method will fall through to DynamicForm.showFieldErrors() to update the display
  - setFieldErrors
```
public void setFieldErrors(java.lang.String fieldName,
                  java.lang.String[] errors,
                  boolean showErrors)
```
    Set field validation errors for some field. The showErrors parameter allows the errors to be displayed immediately. Alternatively, an explicit call to DynamicForm.showFieldErrors(java.lang.String) will display the errors for this field.
    
    Parameters:
    fieldName - field to apply the new errors to
    errors - errors to apply to the field in question
    showErrors - If true this method will fall through to DynamicForm.showFieldErrors() to update the display
  - getFieldErrors
```
public java.lang.String[] getFieldErrors(java.lang.String fieldName)
```
    Returns any validation errors for some field in this valuesManager. If no errors are present, will return null.
    
    Parameters:
    fieldName - the field name
    
    Returns:
    error messages for the field.
  - getItem
```
public FormItem getItem(java.lang.String itemID)
```
    Retrieve a FormItem from this ValuesManager.
    Takes a field 'name' or ${isc.DocUtils.linkForRef('dataPath')}, and searches through the members of this valuesManager for an editor for that field. If found the appropriate formItem will be returned. Note that if a dataPath is passed in, it should be the full data path for the item, including any canvas level 'dataPath' specified on the member form containing this form item.
    Note: Unlike the DynamicForm class, this method will not return an item by index
    
    Parameters:
    itemID - item fieldName or dataPath identifier
    
    Returns:
    form item for editing/displaying the appropriate field, or null if no formItem can be found for the field.
  - addSubmitValuesHandler
```
public com.google.gwt.event.shared.HandlerRegistration addSubmitValuesHandler(SubmitValuesHandler handler)
```
    Add a submitValues handler.

    Parameters:
    handler - the submitValues handler
    
    Returns:
    HandlerRegistration used to remove this handler
