Hi Jürgen,

I did what you say and it's a little bit better.

Thanks

Hi,

I have an add form which a subclass of form.AddForm. It just adds a 'cancel' action.

This is my code:

class AddView(form.AddForm):

Try this here :
      actions = form.AddForm.actions

    form_fields = form.Fields(IDocument).omit('__name__')

    def create(self, data):
        return Document(**data)

    def nextURL(self):
        url = zapi.absoluteURL(self.context.context, self.request)
        return url

    @form.action(u'Cancel', validator=always_good)
    def handle_cancel(self, action, data):
        self.request.response.redirect(self.nextURL())

When I define the 'cancel' action using the @form.action decorator it seems that the 'add' action is lost. That action is defined in my super class.

As a workaround I do the following:

    def handle_cancel(self, action, data):
        self.request.response.redirect(self.nextURL())

    actions = form.AddForm.actions + form.Actions(
        form.Action(u'Cancel',
                    success='handle_cancel', validator=always_good),
        )

but I'm not sure if I'm missing something since my workaround is uglier than the decorator solution.

Best regards,

Lorenzo Gil
