Hi Thierry,

I implement cancel buttons for formlib like this (probably came from
somewhere but I forget where)::

def always_good(form, action, data):
"""Helper for actions - will always validate - useful for cancel
actions"""
return []

class MyAddForm(form.AddForm):
@form.action(_("Cancel"), validator=always_good)
def handle_cancel(self, action, data):
self.request.response.redirect(self.nextURL())

Hope that helps, regards,
Darryl

Any help ?

Have You read subject (this list): "formlib vs. cancel button"? Martin 
Aspeli has similar question, and AFAIK there was some clue/solution (at 
least for Cancel button).


Cheers!
