You're right. It didn't happen to me I could do it this way... Too much soccer watching (with beer).... But, it is desirable that the object used for populating the form and the object used for submitting from a form is the same one.

When you say adaptor, do you mean a generic one which works for all of my model classes or I need to write one per model class? >So, including the adaptor, we are talking about creating maybe two >new classes. In 1.1, a BaseMapForm drops to one (the adaptor). And if >your business tier can already cope with String maps, we've hit >bottom at zero -:o) Is there a BaseMapForm in 1.1b????? I couldn't find it. I know in 1.1b I use DynaBeans to back ActionForms. But I don't I can use Maps.
