Class ActionEventContextHolder

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

public final class ActionEventContextHolder
extends java.lang.Object

Simple holder class that associates a ActionEventContext instance with the current thread. The ActionEventContext will be inherited by any child threads spawned by the current thread.

Used as a central holder for the current ActionEvent in JSF-Spring, wherever necessary: for example, in concrete controller instances. DelegatingActionListener automatically exposes its current ActionEvent here.
