I do envision updates to the database in a models class but simple retrieves are OK IMHO.

Ok, first let me start by noting I don't have much experience yet with QuickForm but have heard good things and I think having you integreate QuickForm would be a great way to validate the usefulness of this MVC package. What you are proposing makes sense. Essentially you trying to move the validation back into the form (which is how Struts handles it). Give me some time to look at QuickForm and I'll get back to you -- Tony Bibbs "I guess you have to remember that those who don't tony@tonybibbs.com hunt or fish often see those of us who do as harmlessly strange and sort of amusing. When you think about it, that might be a fair assessment." --Unknown
