Look at the "handle" and "process" methods of the form.Form class.
Interestingly, they didn't make it to the new form2 framework, but I find'em
a good starting point anyway.

Also, a number of members self.error among them, have been
decentralized, and now each Widget keeps its own data. In fact, the
form2.Form class has grown a "has_errors" method that wasn't previously needed.

Having used the original form framework, I find the diff between form and
form2 quite instructive.


By the way, form2.RadiobuttonsWidget.__init__ is broken, two parameters to
the call of the SingleSelectWidget constructor, at line #428 of widget.py,
survived while they shouldn't have, namely "allowed_values" and "descriptions".
