Hi,

Playing as devil's advocate :-)

Any event can submit a form with proper javascript event capturing code.
Also, submit_widgets are rendered apart from the rest of widgets in the form
render methods. That can be redefined but then again the layout vs. behaviour
dilema can arise.

In any case, I would prefer a more general solution that at this moment I'm
disabled to propose.

Currently, I use to delegate the resolution of these situations to the request
handler, and free form from taking decissions. BTW I think that is one of the
outstanding differences between form2 and form1, although someone can see it
as inconvenient.
