OK, not entirely. :-) The weird thing is that a friend of mine works on the same AS 4.2.1.GA, checked out latest CVS Seam trunk and built this same CMS example project. But he still gets the mentioned exception. What should I be careful about? Or what did you fix to make it go away for me? Our .ear's look quite alike - with fast inspection ... at least the richfaces libs are the same ... My .ear works from me and him. His fails for him and me. :-( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088131#...
