Hi everyone,

Please in the customer/supplier refund I need to get the invoice_line depending to the invoice_id of selected partner for that I had used this one below so any suggestion for how can I get invoice_line (I have used onchange on invoice_id but when I edit invoice line or when I save lines disapper)

'invoice_id' : fields.many2one('account.invoice', string='Invoice number'),

  def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False, submenu=False):

        """

        """

        res = super(kms_invoice, self).fields_view_get(cr, uid, view_id=view_id, view_type=view_type, context=context,

                                                        toolbar=toolbar, submenu=submenu)

        invoice_type = context.get('default_type')

        type = context.get('type')

        invoice_obj = self.pool.get('account.invoice')

        inv =invoice_obj.browse(cr, uid, context=context)

        if invoice_type == 'out_refund' or type == 'in_refund':

            doc = etree.XML(res['arch'])

            for node in doc.xpath("//field[@name='invoice_id']"):

                node.set('domain', "[('partner_id', '=', partner_id),('state','!=','draft'),('type','not in',('out_refund','in_refund'))]")

                setup_modifiers(node, res['fields']['invoice_id'])

            res['arch'] = etree.tostring(doc)

        return res
