We've ran into this problem as well. Setting UseJBossWebLoader=false won't completely fix the problem either, you'll need to make sure you're not specifying the a loader repository in jboss-web.xml either.

We ran into this problem with Seam+Trinidad, and what happens is that Seam's FaceletsRenderer is setting the context class loader to a UCL. We were able to workaround it by re-implement the FaceletsRenderer with one that doesn't set the context class loader.

Pete: is there any documentation describing the reasoning as to why Seam isn't supporting UseJBossWebLoader=true? I'd like to be more aware of the consequences if we do decide to continue on with that configuration.

Thanks!

useJBossWebLoader is a "hack" to force everything onto the same classloader. Why do you need it? The main reason was RichFaces but that now has split out an API.

Hi Pete,

As this may be true, I'm still having troubles with UseJBossWebLoader=false and JSF, eg when using RichFaces' Tree and adviseNodeOpened, throwing this exception:

I don't have this when using UseJBossWebLoader=true, but I'm unable to use my Asynchronous Mail system then, so I'm in some sort of deadlock ;-)

Any suggestions?

Its hard to know what causes that. What is #{fileSystemManager}? where is it in your deployed archive?
