Actually, now you've stimulated a though in me! :) Correct me if I'm wrong, but processPreprocess() fires BEFORE processValidate(), correct? In that case, since I can in fact determine the input after processPreprocess() fires, I can simply call setInput() on the mapping with the new value, and everything should work as expected. Sound about right to you Joe? > I still think using the ComposableRequestProcessor is an easier solution! You didn't answer the question I was hoping you would though :) Is that class based on the CoR-based Struts codebase? If so, while I in no way diagree with you that it's probably the better/easier solution, I'm not quite ready to move to the CoR paradigm with this yet. > Joe -- Frank W.
