To be precise, icefaces file upload gets broken and possibly some other things too that we haven't experienced yet.
We use seam 2.0.0GA, icefaces 1.7DR#3 from svn, jsf 1.2 on glassfish v2

When uploading file, some odd exception of "EJB not found" is thrown.

I have posted full stacktrace already at icefaces forum at
http://www.icefaces.org/JForum/posts/list/6613.page

Example source
http://www.flamebox.org/fserver/soovexample.rar
Example ear package
http://www.flamebox.org/fserver/soov.ear

When executed, simple page is displayed where you can select file to upload, upload it, and also see the progress of the upload.

Ear has <transaction:ejb-transaction/> in components.xml

When I upload the file and icefaces component tries to send content to browser, exceptions

When I remove the <transaction:ejb-transaction/> from components.xml, file upload works correctly, when I add it, things stop working.
Is this seam related issue and how and if can I overcome the EJB not found exception and EJB being associated with incomplete transaction during upload ?
