public class PreRemoveFromViewEvent extends ComponentSystemEvent
When an instance of this event is passed to SystemEventListener.processEvent(jakarta.faces.event.SystemEvent)
or
ComponentSystemEventListener.processEvent(jakarta.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.
