Re: Transformation Exception
Greg, I had a similar error and fixed it updating the Javassist dependency (now my project depends on javassist:javassit:3.9.0.GA - the old one was jboss:javassist:3.6.0). Co-workers told me that they used to follow certain "code conventions" that prevented Javassist to write wrong transformations (eg. using getter/setter instead of direct property access, don't put a lot of code inside onActivate() - put the logic on a private method and call the method inside onActivate()).

Re: Transformation Exception
Thanks Howard,
I changed the project to compile as jdk 1.5 and removed any @Override
annotations. The code compiles but still generates the same error under
tomcat6. I get the same error under Jetty 7. The solution for me is to
run Jetty 6 in production which doesn't seem to produce any of these errors.
I understand that JavaAssist will be removed from Tapestry 5.2. Any idea
on when it will be released yet?
Also, I've written my first ajax component and am really starting to see
the potential of the Tapestry model.
Regards,
Greg.

Your best bet for dealing with these issues is to first try compiling
for JDK 1.5, even if you are deploying on 1.6. You can see why we're
