org.apache.beehive.netui.pageflow.GlobalApp

Base class for user-defined global state and fallback controller logic. A specific instance of this class (based on the Global.app/Global.java source file in the "global" package) is created and stored in the user session before any {@link PageFlowController} is created, and unless it is explicitlyremoved from the session, it is not freed until the session is invalidated.

Actions that are not handled by the current {@link PageFlowController} "bubble" up to thecurrent GlobalApp instance, which gets a chance to handle them in user-defined action methods. Uncaught exceptions also bubble through the GlobalApp instance, which has a chance to catch them.

Data in the current GlobalApp instance can be accessed by databinding tags using the globalApp scope. @deprecated Use a {@link SharedFlowController} instead. @see PageFlowController
