I guess that lots of people are waiting for this .. there are so many interesting developments on the horizon with JSF 2/2.1, Web Beans, and Bean Validator!
Did you try turning off @DEBUG@ in components.xml?
It was already off. I got further by simply removing the seam-debug jar from the classpath but then I ran into other compatibility issues with RichFaces so I gave up. I guess it's quite understandable, with the specification not even being final and all. Still, it would have been nice to start using some of the new features.
