Thanks Rahul, Sorry for posting on dev list but I would request you to please end my discussion on this list from any subsequent post I will use user list ,I just dont want to loose context , Hope you will understand.
I have one more simple question is anybody aware of any SCXML editors ( if possible free or open source ) , Rahut are you aware wich software is used in the slides you mailed me .
