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!

   Hi,
 
 I have several formlib.form.AddForm subclasses in which I've created a
 custom Action via @action(...).
 My problem is that I'd like to be able to launch some of these actions
 (but not all of them, it's action specific) without executing
 automatic formlib controls (actually, for example, even a simple
 Cancel button which should just redirect the browser actually raises
 an exception when required fields are missing).
 
 Any help ?

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
