Max, It makes a BIG difference when you say that you can't reproduce what i've described while using seam 2.0 In fact we were not completely synchronized (please be patient i'll explain all). I've been searching and deeply testing these last three days and I'm happy because all my troubles are gone :-)) To be short: Everything works fine with JBT 3 RC1, Seam 2.0, and eclipse Ganymede with WTP 3.0.3 Everything also works fine with JBT 3 RC1, Seam 2.1.1 GA (yes, the last one), eclipse Ganymede with WTP 3.0.3 Here are the two combinations that works perfectly with Seam project. While you were testing seam 2.0 with ganymede and WTP 3.0.3 I was using seam 2.1.RC1. That's the reason why we were not able to produce the same results. I think that these two working combinations should be described somewhere to prevent users from loosing times doing what I did ... In any case, I'm thanking you for the time you spent for solving this problem. Meissa View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4198710#...
