Seam 2.0 beta problem

kruno Jul 3, 2007 6:21 AM

I started to migrate from seam 1.21 to 2.0 (jboss 4.2), I followed migration tutorial, and examples in seam 2.0.
The problem is when I try to call some bean with ajax4jsf component or tomahawk component I get exception, but with h:commandButton or s:button
things work.

Thanks in advance for any help Kruno.

Exception:

11:08:44,536 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
