FacesListener, SystemEventListener, EventListener

Enclosing class:

StateContext

public class StateContext.StatelessAddRemoveListener
extends StateContext.NoopAddRemoveListener

An AddRemoveListener that implements the new dynamic component strategy where no state is managed by the listener itself. Instead, we use expando attributes on the dynamic components (and their parents) to track/preserve the dynamic nature of these components.
