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() {
...
}
...
}
