Class PostAddToViewEvent

java.lang.Object
All Implemented Interfaces:
Serializable

public class PostAddToViewEvent 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 and that either that instance or an ancestor of that instance was just added to 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.

The implementation must guarantee that Application.publishEvent(jakarta.faces.context.FacesContext, java.lang.Class<? extends jakarta.faces.event.SystemEvent>, java.lang.Object) is called in the following cases.

  • Upon the initial construction of the view, when each instance is added to the view.

  • On a non-initial rendering of the view, if a component is added to the view by the View Declaration Language implementation as a result of changes in evaluation result of Jakarta Expression Language expressions referenced by VDL tags such as c:if, ui:include, and other tags that dynamically influence the assembly of the view.

  • If a component is programmatically added to the view using the Java API directly. For example, user code manually adds children using comp.getChildren().add(), where comp is a UIComponent.
