i am hoping this saves some people some headaches but i updated jsf-api.jar and jsf-impl.jar w/in my modules directory in glass fish and now my code is working as you think it should... Its beautiful... I hope this saves someone some time. I was using an up to date version of glassfish and i guess my mojarra related jars where old?
