I was hoping that going through the exercise of struggling through those gaps would help me arrive at a better understanding of all things zope(a lofty goal I'm sure). thanks so much for the info. I'll check out z3c.form. But if I understand what you are saying about the request needing to be marked with the IFormLayer interface, I would assume an adapter could be configured to provide that. I'll try that first anyway. -- Thomas G. Willis
