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.
