public class RequiredIfValidator
extends Validator

RequiredIf type validators should be specified with a RequiredIfFunction, which has to be passed to setExpression(), and takes two parameters:

• item - the DynamicForm item on which the error occurred (may be null)
• value - the value of the field in question

When validation is perfomed, the expression will be evaluated - if it returns true, the field will be treated as a required field, so validation will fail if the field has no value.
