Ummmm..... this sounds bizaare enough to make me question the engineering behind this. Seems like it would be better to put the code your trying to execute into a business logic layer, or otherwise outside the action class to begin with. However, I'll assume you have no choice... However, in answer to your qustion... have the action class check a session attribute first, then check the request parameter. > > (if you're wondering why my Actions are setup like this, it's because > they all extend the same abstract Action class that has logic to do > processing based on the request parameter... so what's really > happening > is that each Action is executing the same thing but i'd like > to be able > to have them do different things) > > any suggestions is much appreciated and thanks in advance, > > woodchuck > > > > > _______________________________ > Do you Yahoo!? > Express yourself with Y!
