  NavigateSplitPaneTask | Causes the list pane component to load data and update its title based on the current selection in the source pane.
  PrintCanvasTask | Print canvas by showing print preview.
  Process | A instance of Process represents a stateful process executing a series of Tasks, which may be: user interactions calls to DataSources (hence: any database or web service) arbitrary code other Processes A Process is stateful in the sense that it maintains `state` across the different tasks that are executed.
  ProcessElement | A ProcessElement is an abstract superclass for elements involved in a `Process`, such as a `Task` or `DecisionTask`.

  PropertyValue | Identifies a property name and value to be assigned to a component by the `SetPropertiesTask`.
  ResetPasswordTask | Show user password reset dialog by opening the `Auth.resetPasswordURL` in another tab or window.
  ScriptTask | Task that executes arbitrary code, either synchronous or asynchronous.
  SendTransactionTask | Sends any currently queued DataSource operations, as a single transactional request to the server.
  ServiceTask | A ServiceTask is an element of a `Process` which calls a DataSource operation, optionally using part of the `process state` as inputs or storing outputs in the process state.
  SetPropertiesTask | Gets the value properties from a component and makes them available within the workflow as the `last task output`.
  SetScreenDataTask | Sets an embedded screen's `dataContext` with the `dataContextBinding` evaluated in the scope of this task.
  SetTitleTask | Sets the title of a tab, section, window, label, button, form control or facet chart.

  ShowNotificationTask | Show a message which fades out automatically using `Notify`.
  StartProcessTask | Task that executes another `Process` inside the current one.
  StartTransactionTask | Starts queuing all DataSource operations so they can be sent to the server all together as a transaction.
  StateTask | StateTask can either copy fields of `Process.state` to other fields, or apply hardcoded values to `Process.state` via `value`.
  Task | A Task is an abstract superclass for `Process` and for all Task types that can be involved in a Process, such as a `ServiceTask`.
  TaskDecision | Identifies a potential decision (branch) within a `MultiDecisionTask`.
  UserConfirmationGateway | Chooses one or another next process element based on confirmation of a message shown to user.
  UserConfirmationTask | Chooses one or another next process element based on confirmation of a message shown to user.
  UserTask | A task that involves showing a user interface to the end user allowing the user to view and input data and press a button (or do some other UI gesture) to complete the task.
  XORGateway | Chooses one or another next process element based on AdvancedCriteria applied to `Process.state`.
