    _inherit = 'account.voucher'

    def fields_view_get(self, cr, uid, view_id=None, view_type=False, context=None, toolbar=False, submenu=False):
        """
            Add domain 'allow_check_writting = True' on journal_id field and remove 'widget = selection' on the same
            field because the dynamic domain is not allowed on such widget
        """
        if not context: context = {}
        res = super(account_voucher, self).fields_view_get(cr, uid, view_id=view_id, view_type=view_type, context=context, toolbar=toolbar, submenu=submenu)
        doc = etree.XML(res['arch'])
        nodes = doc.xpath("//field[@name='journal_id']")
        if context.get('write_check', False) :
            for node in nodes:
                node.set('domain', "[('type', '=', 'bank'), ('allow_check_writing','=',True),('your_field','=','value')]")
                node.set('widget', '')
            res['arch'] = etree.tostring(doc)
        return res
