dw.web.FormElement
dw.web.FormGroup
The class is the central class within the whole form handling. It is the container element for fields and other form elements. A form group can contain other forms, also called sub-forms. Access to the elements of a form is provided via an index based access or via an associative array access. For example, the field "firstname" can be accessed with the expression "myform.firstname".
All Known Subclasses
Properties
childCount  :  Number  (Read Only)
The number of elements in the form.
error  :  String  (Read Only)
A form-wide error message. If no error message is present the method returns null.
object  :  Object  (Read Only)
The object that was bound to this form group.
submittedAction  :  FormAction  (Read Only)
The action that was submitted with the last request. The action is set independent whether the form must be valid for this action. The method returns null if no action at all was submitted with the last request for this form group.
triggeredAction  :  FormAction  (Read Only)
The action that was triggered with the last request. An action is only marked as triggered if the constraints regarding form validation are meet. The method returns null if no action was marked as triggered.

Method Detail
accept
accept() : void
The method copies the value from a form into the object, which was previously bound to the form. The method is equivalent to the pipelet AcceptForm. This method is equivalent to the call formgroup.copyFrom( formgroup.object ).

copyFrom
copyFrom(obj : Object) : void
The method updates the form with the values from the given object. The method call is basically equivalent to the pipelet UpdateFormWithObject. The method not only copies the value, it also binds the object to the form. Binding means that the form keeps the information from which objects the values were taken. This can be used for two purposed, first for lists it makes it easier in the code to find the associated object, for example in case of a relate action, and it allows to copy back the values from the form into the object (see accept()). Because of this bind behavior, the operation is also sometimes called a bind-operation.
Parameters:
obj - the object from, which the values are read

copyTo
copyTo(obj : Object) : void
The method updates the object with the values from the form. The method call is basically equivalent to the pipelet UpdateObjectWithForm.
Parameters:
obj - the object, which is updated from the form

getChildCount
getChildCount() : Number
Returns the number of elements in the form.
Returns:
the number of elements in the form.

getError
getError() : String
Returns a form-wide error message. If no error message is present the method returns null.
Returns:
a form-wide error message or null.

getObject
getObject() : Object
The object that was bound to this form group.
Returns:
the bound object.

getSubmittedAction
getSubmittedAction() : FormAction
Returns the action that was submitted with the last request. The action is set independent whether the form must be valid for this action. The method returns null if no action at all was submitted with the last request for this form group.
Returns:
the action that was submitted with the last request or null.

getTriggeredAction
getTriggeredAction() : FormAction
Returns the action that was triggered with the last request. An action is only marked as triggered if the constraints regarding form validation are meet. The method returns null if no action was marked as triggered.
