Re: PhaseListener/SetFocus Question

[Mike Kienenberger]

Yes, phase listener doesn't seem like the place to handle it.

How many submit buttons do the forms have?  It'd seem like you'd want
to do this in the action or actionListener for each of the UICommands
instead of in a phase listener.

If you're going to use a phase listener, you'll need to determine
which form was submitting.   Don't know how that's done off the top of
my head, but you could set a breakpoint on an action and see how
things got there.

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?

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() {
 ...
}
...
}
