public class PreRemoveFromViewEvent extends ComponentSystemEvent
When an instance of this event is passed to
SystemEventListener.processEvent(javax.faces.event.SystemEvent)orComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that thesourceof this event instance is aUIComponentinstance that is about to be removed from the view. Therefore, the implementation may assume it is safe to callUIComponent.getParent(),UIComponent.getClientId(), and other methods that depend upon the component instance being added into the view.- Since:
