This related field working fine in `odoo 9`, but not in `odoo 10`. The field `customer_id` not updated when I create a new record with `nomor_hp_id`.

```py
nomor_hp_id = fields.Many2one(
    string='Nomor hp',
    comodel_name='nomor.hp',
    ondelete='cascade',
)
customer_id = fields.Many2one(
    string='Customer',
    related='nomor_hp_id.customer_id',
    ondelete='cascade',
    store=True,
    readonly=True,
)

```

Try to start new database but the result still not updated.
