MessageArea 

The MessageArea UI element represents a placeholder that specifies where messages, such as error messages or warnings, should appear in the view.

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 the MessageArea UI element should 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.

For more information, see Messages.
