That's correct - we are moving from JBoss AS 4.0.4 to 4.2.1. I have been looking at the wiki and trie to replace the RI JSF implementation with MyFaces but that doesn't seem to work when the Portal is deployet in the AS. We've also tried to bundle the MyFaces Implementation in our Portal War file, but then we faces a lot of other ClassCastExceptions etc. Has anyone succeeded to use MyFaces portlets together with Portal 2.6?
