MessageArea 

The MessageArea UI element represents a placeholder that specifies how messages such as error messages and warnings are to be depicted in the view.

Under certain circumstances, the Web Dynpro Framework changes the position specification of the MessageArea UI element if other targets such as portal mechanisms for displaying error messages have priority.

Note that if the MessageArea UI is to be visible, you should also make sure that the view that contains the UI element is visible (the visibility of the view and UI element should match).

For more information, see Messages.
