Right. I used something like this here in a custom form:


    @zope.formlib.form.action(
        _("Apply"),
        condition=zope.formlib.form.haveInputWidgets)
    def handle_edit_action(self, action, data):
        super(EditForm, self).handle_edit_action.success(data)
        self.request.response.redirect(self.nextURL())
        return "Redirect..."
