hello Anders

I have made some changes in your piece of code.Try to understand the hint/change.

hope this hint/change may help you or may solve your problem

@api.multi
    def moves_xml(self):
        view_id = self.env.ref('module_name.record_id_of_form').id
        context = self._context.copy()
        return {
            'name':'form_name',
            'view_type':'form',
            'view_mode':'tree',
            'views':[(view_id,'form')],
            'res_model':'account.export',
            'view_id':view_id,
            'type':'ir.actions.act_window',
            'res_id': account.id,
            'target':'new',
               } 

Thank you both!

@api.multi did the thing

I tried @api.one and others with no luck before i got back to v7-syntax.
