(was RE: Benefits of Dynaforms) ok, this one sentence in ted's post caught my eye: > I rarely write custom Actions any more. whoah. how is this possible? most of our web pages represent some sort of database operation: displaying, creating, updating, or deleting. i can see how you can minimize the amount of code that would vary in individual Action classes, but i don't see how could eliminate the need for subclassing altogether. maybe i'm just completely misunderstanding here. could you elaborate on your process? thanks, ab > Ideally, a framework like Struts should just be passing gestures > and data back and forth between the presentation pages and > business tier.
