Thanks for your excellent article. Google translate helped me to understand your German text :) Instead of going via the constraint approach I will try using your approach. I see many people using z3c.form it makes me wonder whether to follow their trail or to stick with zope.formlib. -- Joshua Immanuel HiPro IT Solutions Private Limited http://hipro.co.in
