Good call Chris! I didn't realize that. The context solution Maurizio
offered now works for me. Pros/cons to both
approaches. The context approach could be confusing to the uninitiated on
the UI side. Pop/push could be confusing or mysterious at the interceptor
level (again, for the casual Struts coder). The context solution will be
the quickest for me (already done), so I guess that's the winner of the
coin toss.
Thanks again everyone!
