public class InvokeActionEventListener extends DefaultPhaseListener implements SystemEventListener
PreInvokeActionEvent and PostInvokeActionEvent events are
properly published.
This phase listener is already registered by OmniFaces' own faces-config.xml and thus gets
auto-initialized when the OmniFaces JAR is bundled in a webapp, so end-users do not need to register this phase
listener explicitly themselves.

InvokeActionEventListener()
This constructor instructs the
DefaultPhaseListener to hook on PhaseId.INVOKE_APPLICATION and
subscribes this instance as a SystemEventListener to the PostValidateEvent event. |
| Modifier and Type | Method and Description |
|---|---|
void |
afterPhase(PhaseEvent event)
Publish the
PostInvokeActionEvent event on the components which are been collected in
processEvent(SystemEvent). |
void |
beforePhase(PhaseEvent event)
Publish the
PreInvokeActionEvent event on the components which are been collected in
processEvent(SystemEvent). |

|
void |
processEvent(SystemEvent event)
If the validation has not failed for the current faces context, then check if the
UIComponent which
passed the isListenerForSource(Object) check has any listeners for the PreInvokeActionEvent
and/or PostInvokeActionEvent events and then add them to a set in the current faces context. |

subscribes this instance as a SystemEventListener to the PostValidateEvent event. This allows
