It depends. I prefer not to build my forms from objects. Sometimes, the
form is not like the object where the data is going into, or maybe the
form spans multiple relationships in a join.

When I need to customize the form validation heavily...aka errors
messages, validaiton profiles, load those from files, etc, I stick with
FormValidator::Simple and/or Data::FormValidator.

When I'm doing forms that are 1-1 with the objects (CRUD-like
operations), then I'm all for widget all-in-one form validators/generators.

Try as all of them have, there is not one solution in this area, and
this topic is akin to vi vs. emacs in some respects.

THe one true answer is: it depends on the situation, the requirements
and how each app needs to go about doing it in its problem domain.
