public class PreRenderComponentEvent 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 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.
