Class DelegatingActionListener

java.lang.Object
  de.mindmatters.faces.application.DelegatingActionListener

All Implemented Interfaces:

java.util.EventListener, ActionListener, FacesListener

public final class DelegatingActionListener
extends java.lang.Object
implements ActionListener

This action listener implementation processes action events during the Apply Request Values or Invoke Application phase of the request processing lifecycle (depending upon the immediate property of the ActionSource that queued this event.

Usually this action listener invokes the specified application action method of the encapsulated action listener of the underlying JSF implementation. But if there can be found an action listener in the request the action method of this one will be invoked.

Furthermore this action listener populates the action event given to the action method as a thread local variable via the ActionEventContextHolder.
