I would just get used to the idea of using z3c.form. It will be especially helpful to look at z3c.formdemo, which has examples that I think are highly relevant to your usecase. You'll end up writing a less code that does more. -- Paul Carduner http://www.carduner.net _______________________________________________ Zope3-users mailing list Zope3firstname.lastname@example.org http://mail.zope.org/mailman/listinfo/zope3-users
