public class PreRenderComponentEvent extends ComponentSystemEvent
When an instance of this event is passed
to SystemEventListener.processEvent(javax.faces.event.SystemEvent)
or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent)
, the listener
implementation may assume that the source
of this event
instance is the UIComponent
instance that is about to be
rendered and that it is safe to call UIComponent.getParent()
, UIComponent.getClientId()
, and other
methods that depend upon the component instance being in the
view.
