Major Description
I have been experimenting with the dormant support for MyFaces added by AS7-5649. After setting up a recent JBoss snapshot build (#1292) as described in that issue (adding commons-digester, myfaces-api, and myfaces-impl to modules), I attempted to use my application. It deploys successfully (which is a big step, before it failed due to AS7-5849 / AS7-1628), but as soon as I try to log in, it blows up with this stack trace:

After some experimentation, I determined that this is due to the use of the MyFaces CODI extensions in the project. If I remove the CODI libraries from the project (which is doable because it is only used in a few places, but not ideal), I do not get this exception. CODI has been tested against MyFaces, and I cannot find anyone else experiencing this problem, so I believe JBoss (or perhaps Weld) is doing something that CODI does not expect.
