Don't have any more ideas, but generally, the message "cannot find
bean in any scope" means exactly what it says: The bean is not in a
scope where it can be found. Which means that either it is set in
request scope, and attempted to be used in a different request
(typically what happens when you do a redirect), or that it has not
been set at all. Also, keep in mind that the request/response cycle is
a little bit different in a portlet than in a regular web application,
so you might have to re-think what you're trying to do.
