Ok thanks - happens to be what I'm trying at the moment. I have your booking example in the midst of being converted to a portlet with ear deployment. To me it seems currently that the problem may tie up with the StartupServletContextListener exception that is thrown when MyFaces sees it is not included in the config, but I may be wrong - lots of config to check through. Incidentally, The Portal guys are using a different ajax framework for Portal v2.6 developement. I hope the to will cohabit ok. Andy.
