Answer 1

I got also problems with myfaces-extensions using x tags. The conflict is due to the fact that myfaces is a very old solution and if your other libraries are uptodate the versions won't match. As posted at tomahawk inputfileupload uploaded file is null in my answer you should use tomahawk t tag and libraries related to it. Actual solution is posted in the main answer of that very same link.
I'm pretty sure this will do the thing. Tick my answer if the post included the answer to your question in its wiki-link :)
