Hi Max,
That's indeed a FE bug, as you can see the only point where TG widgets
kick in is to call to_python on the form Schema.
Regarding your fix, maybe you can post it on FE trac and in the
meanwhile put it inside tg.validators to fix the bug (add a note so
that we track it maybe), Kevin?
Ciao
Michele
