Subject Re: (RE-POST) RE: using getInputForward vs new ActionForward(mapping.getInput())
Date Fri, 11 Jul 2003 14:03:26 GMT
there is a way you won't like and I don't like either.

have the input point to a mapping that is exactly the
same and has a different parameter.  Change the action
to check for it and just render the jsp.
