FormSets have ADDOBJECT() methods like any other container, so you can add Forms to the FormSet on a pay-as-you-go basis. Having a formset with a single form is about equivalent to having just the Form since the FormSet is so lightweight...

I know that when I started working with VFP, they had a rather bad reputation - something of being a poor replacement for Screen Sets in older Fox versions. But the example you give is a very good idea, especially since I have always wished that the Custom class had a Private data session.

By the way, have you recently started writing in the UT? I know your work, but just today saw a post from you.
