Member variable CxpAbstractPage():Data Foundation
References a container object which handles the data associated with the page.
The object in :Data is a container for state information. All information assigned to the member variables of the data object is automatically saved and restored as needed (automatic persistence). Assigning a value to a member variable not only stores the respective value, but also creates the member variable if it does not exist yet.
The data stored in the container is page-specific. This is in contrast to :Session, which has a user/session-specific scope, or :Application which maintains information with a context which is application-wide. The following code shows how the :Data container can be used from within your page/application.
