Ah, ok, I see. And constraints are enforced when a data-object is
given to the process-method, regardless of whether the object actually
contains a key for the field.

It makes sense if you know how it works :-)

So, currently I can't display a form like the one in my example, if I
call the process-method with a data-object.

That would certainly solve my problem. Should I try to whip up a
patch, or?
