Hi,
I've run into a problem using a4j:mediaOutput from the ajax4jsf library for displaying
an image retrieved from my db.
When I'm trying to load the page I get the following exception from the
ajax4jsf-call:

Alle the other ajax4jsf-tags work fine in my environment. It looks like it fails when
trying to resolve an EL expression. I am not resolving any expressions in my code of the
method for generationg the outputstream.
Even if I don't declare it as Seam component but instead as an mbean (so not using any
Seam-related stuff inside) I get the same exception.
I am using jboss-seam-CVS.20061030 with AS 4.0.5, myfaces and facelets and the
SeamFaceletViewHandler for the EL enhancements.
Any ideas?
