Thanks Lorrie.
I hadn't realized that one could return a null
mapping. More than likely I will redirect to the
referring url using a dispatcher.
Does that sound like the best way to redirect to the
referring URL/URI? This url would more than likely be
another "blaBla.do" page.
I am presuming that if I tried to generate an
ActionMapping on the fly or use a global forward, that
there would be more work with little added benefit.
