Hi every one This might allready have been proposed and done but I haven't seen it around and it works fine for me to create all forms from one definiton and one binding file. (multiple page search form). The problems were with the widgets that weren't used couldn't be validated, and therefore were blocking.
This solution uses JXTemplate in the definition and the bind, that I cut up using only jx:if tags. On declartion in FLow I have dynamic constructions of the bind and the model (cocoon:/myform_model, cocoon:/myform_bind) to go through the cut up , so according to what I need in myform_template I have the associated cut up in model and bind, I only keep the jx:if block concerned for "myform" and don't bother with the rest. and voila. Regards Tibor
