Consider this function:

    @api.multi
    def create_invoice(self):
        """ Create a invoice refund
        """

        self.ensure_one()
        if not self.sure:
            raise UserError(
                _("Validation error!"),
                _("Please confirm that you know what you're doing by"
                  " checking the option bellow!"))
        if (self.invoice_id and self.invoice_id.company_id.jour_id and
                self.invoice_id and self.invoice_id.company_id.acc_id):
            inv_id = self.action_invoice_create(self,
                                                self.invoice_id)
        else:
            raise UserError(
                _('Validation error!'),
                _("You must go to the company form and configure a journal"
                  " and an account for damaged invoices"))
        return self.new_open_window([inv_id], 'action_invoice_tree1', 'account')

This is from a migration I'm doing from v8 to v10 community.

This method originally looked like this:

    def create_invoice(self, cr, uid, ids, context=None):
        """ Create a invoice refund
        """
        context = context or {}
        wizard_brw = self.browse(cr, uid, ids, context=context)
        inv_id = context.get('active_id')
        for wizard in wizard_brw:
            if not wizard.sure:
                raise osv.except_osv(
                    _("Validation error!"),
                    _("Please confirm that you know what you're doing by"
                      " checking the option bellow!"))
            if (wizard.invoice_id and wizard.invoice_id.company_id.jour_id and
                    wizard.invoice_id and wizard.invoice_id.company_id.acc_id):
                inv_id = self.action_invoice_create(cr, uid, ids, wizard,
                                                    wizard.invoice_id, context)
            else:
                raise osv.except_osv(
                    _('Validation error!'),
                    _("You must go to the company form and configure a journal"
                      " and an account for damaged invoices"))
        return self.new_open_window(cr, uid, ids, [inv_id],
                                    'action_invoice_tree1', 'account')

This method, checks if fields `acc_id` and `jour_id` are specified on `company_id`.

Right now, it throws me this:

Any ideas on this?
