Yes, the server log has two different kinds of error messages.

The first is:

I think you’re right that the problem occurs before invoking PD4ML. We debugged line by line through the invoking JSP. In the cases when the app fails we found a JSF call that also fails (it’s trying to access a managed bean from another scope). Since it works sometimes, I guess that specific line is not at fault but that something else has made the desired bean go away.

But who’s clobbering the session?
