This class is used to register the JSF ELResolver stack with the JSP container.

We overload it a bit to set a bit on the ApplicationAssociate stating we've processed a request to indicate the appliation is fully initialized.

After the first request, this PhaseListener will remove itself from all registered lifecycle instances registered with the application.

public synchronized void afterPhase(PhaseEvent event)

Implements javax.faces.event.PhaseListener.afterPhase.

Handle a notification that the processing for a particular phase has just been completed.

When invoked, this phase listener will remove itself as a registered PhaseListener with all Lifecycle instances.

Parameters
event:PhaseEvent

Doc from javax.faces.event.PhaseListener.afterPhase.

the phase event.

public synchronized void beforePhase(PhaseEvent event)

Implements javax.faces.event.PhaseListener.beforePhase.

Handle a notification that the processing for a particular phase of the request processing lifecycle is about to begin.

The implementation of this method currently calls through to populateFacesELResolverForJsp(javax.faces.context.FacesContext).

Parameters
event:PhaseEvent

Doc from javax.faces.event.PhaseListener.beforePhase.

the phase event.

Annotations

getPhaseIdback to summary
public PhaseId getPhaseId()

Implements javax.faces.event.PhaseListener.getPhaseId.

Return the identifier of the request processing phase during which this listener is interested in processing javax.faces.event.PhaseEvent events. Legal values are the singleton instances defined by the javax.faces.event.PhaseId class, including PhaseId.ANY_PHASE to indicate an interest in being notified for all standard phases.

We return PhaseId.ANY_PHASE.

Returns:PhaseId

Doc from javax.faces.event.PhaseListener.getPhaseId.

the phase id.

Annotations
@Override
populateFacesELResolverForJspback to summary
protected void populateFacesELResolverForJsp(FacesContext context)

Populate the FacesCompositeELResolver stack registered with JSP if a request is being processed for the very first time. At the application initialiazation time, an empty CompositeELResolver is registered with JSP because ELResolvers can be added until the first request is serviced.

Parameters
context:FacesContext

- the FacesContext for the current request
