I am returning a dynamic domain from a server action in Odoo with the following code. Please note I am using a hosted version of Odoo online, so I am doing this through the Odoo UI. Actions are returned by assigning `action = {...}`:

action = {

    'domain': {

        'route_id': [('id', 'in', record.x_all_route_ids.ids)]

    }

}

This server action is triggered when the `product_id` field changes for a `sales.order.line`. When viewing a sales order, the sale order, if I change the product_id for one of the sales order lines, the domain for the `route_id` field is updated as expected.

However, the domain is changed for all of the `route_id` fields in the sale order line tree view. In other words, if there are 3 lines in the order, and I change the product_id for one of them, I want the domain to change for just that line's route_id field, not every route_id field in the sale order.

Is what I'm seeing the expected behavior, and is there any way to accomplish what I want instead?
