public class PreRemoveFromViewEvent 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 a UIComponent
instance that is about to be
removed from the view. Therefore, the implementation may assume it
is safe to call UIComponent.getParent()
, UIComponent.getClientId()
, and other methods that depend upon the
component instance being added into the view.
