RE: PhaseListener/SetFocus Question

[Tom Innes]

Thanks for the suggestion Matthias,

Unfortunately that is exactly what I was doing.

My suspicion is that since 

countryQBE is a Managed Property of countryForm and
countryForm is a Managed Property of stateForm 

that all three Phase Listeners fire.  Unfortunately I don't see a way to
distinguish between them. Does anybody know of a way?

Tom

JavaServerFaces in Action mentions on page 437 that you can register a
phase listerner with a bean. The example shows a bean that refreshes a
list before phase RENDER_RESPONSE. Maybe this helps:

public class MyBean() {

public MyBean() {

LifecycleFactory lifecycleFactory = (LifecycleFactory)
FactoryFinder.getFactory(FactoryFinder.LIFECYLE_FACTORY);
Lifecycle lifecycle =
lifecycleFactory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
lifecycle.addPhaseListener(
new PhaseListener() {

   public void beforePhase() {
      refreshList();
  }

  public void afterPhase() {
  }

   publid PhaseId getPhaseId() {
      return PhaseId.RENDER_RESPONSE;
  }
});

 protected void refreshList() {
 ...
}
...
}
