Hello, I have Odoo8.

I have this field in model 'product.pricelist.version'

pagos_realizados = fields.Many2many('account.voucher', 'pagos_vouchers', 'id_pago', 'id_voucher', string='Pagos realizados', domain=[('es_acopio', '=', True), ('partner_id.customer', '=', True), ('fue_usado', '=', False)])

And this field in 'account.voucher' model

pricelist_version = fields.Many2many('product.pricelist.version', 'pagos_vouchers', 'id_voucher', 'id_pago')

The field 'fue_usado' is a field of model account.voucher, which is a computed field, is false if the voucher is related to any pricelist; in other cases is true.

I can check by a view that the 'fue_usado' field is FALSE in various vouchers, but the domain not filters it. The domains works correctly with the two first rules, but ignores the third. Why? Thanks!
