Thanks for your reply. I have checked after removing the clientvalidators but now I am getting following exception. After which I think the actual problem is with the binding attribute of t:panelGroup but I am not understand why this happening because when I was in jsf 1.1 its working fine. What change lead me to this issue? any suggestions. One more thing the page renders fine for the first time. When i click on any command link or button it fails to post it back to server.
