1. Re: Seam and non-Seam application classloader issues
From what I could find out the SeamPhaseListener (loaded from jboss-seam-2.2.1.CR1.jar!/META-INF/faces-config.xml) always registers itself for any JSF/Facelets application.
So I think this listener should check if an application for is a seam application, before doing anything.

3. Re: Seam and non-Seam application classloader issues
The patch provided above against Seam 2.2.1.CR1 stops the phase listener from doing anything on non-seam applications. I patched my local jboss-seam-2.2.1.CR1.jar and it works this way.
