MessageArea
Definition
The MessageArea UI element represents a placeholder that specifies where messages, such as error messages or warnings, should appear in the view.
If there is a suitable MessageArea instance, all messages appear in this instance. Otherwise, the messages appear in a separate window that is similar to a status bar and appears at the bottom of the screen. You can use a MessageArea instance when it belongs to the layout of the associated view.
You cannot set the enabled property to the value false and can only bind this property to a read-only context attribute of type boolean with the value true.
You cannot set the visible property to the values none or blank and can only bind this property to a read-only context attribute of type com.sap.ide.webdynpro.uielementdefinitions.Visibility with the value “VISIBLE“.
If there is more than one suitable IWDMessageArea instance, the first instance created is used
Under certain circumstances, the Web Dynpro Framework changes the position specification of the MessageArea UI elements, if other targets have priority, for example, portal mechanisms for displaying error messages.
If you want the MessageArea to be visible, make sure that the view that contains the UI element is also visible, that is, the visibility of the view and the UI element should match.
The tooltip property does not affect the appearance of the UI element.
