I found in SeamPhaseListener class,
at the beginning of beforePhase(), it calls
Lifecycle.setPhaseId(event.getPhaseId());
and then at the end of the method, it calls Lifecycle.setPhaseId(null);
Once I extend the SeamPhaseListener class and override the method like this
public class PatchShaleSeamPhaseListener extends SeamPhaseListener {
@Override
public void afterPhase(PhaseEvent p_event) {
super.afterPhase(p_event);
//Patch for Shale Remoting error
Lifecycle.setPhaseId(p_event.getPhaseId());
}
}
It fixed the NPE, and all my custom MethodBindingProcessors are working
again, but I am not sure what are the side-affects on Seam now... I will
ask Gavin about this.
Hmm ... Gavin's comment seems more about using the Ajax support in MyFaces
(indirectly, via the InputSuggestAjax) component, not about using Seam with
Shale. I presume you are not using those components?
I'll have to look into this, but after tomorrow (I'm doing two sessions
about Shale at ApacheCon).
