Subject Re: Dynamic form property names
Date Tue, 30 Dec 2003 16:39:24 GMT


  Sorry but I haven't quite catch what you looking for...
  Do you want to create a form in runtime? Is that it?

  If you're using a DynaForm it already has map. You can't set new
properties to the form (it was built based on a DynaClass) but, if you
extend DynaForm to a XDynaForm and make XDynaForm implement Map maybe you
can set new properties on your new form. I used this approach (the
DynaBean/Map extension) to start using DynaBeans with JSTL and, maybe...
just maybe it can help you set new properties on your form. I can send you
the class, if you want.

  As I said, I haven't tried this (the runtime form approach) and I don't
know if this is what you are looking for...
