Hi,

i've just created a model like this:

    _name = 'sale.order.package'

    name = fields.Char(string='Package Name', readonly=True, copy=False)

    weight = fields.Float()

    sale_order_id = fields.Many2one('sale.order')

    picking_id = fields.Many2one('stock.picking')

And in sale.order form, i've created a new tab (page) in order to create the package. When creating a new package from a Sale Order, i can set by default the current sale.order id with "context", but i don't know how to apply a domain in the picking_id field. I mean, when creating a package, i would like to display the picking_ids related to my sale.order, not all picking_ids. How could i do that? I'm triying with "domain" but it doesn't work:

                    <field name="package_ids"

                           widget="one2many_list"

                           domain="[('picking_id', 'in', picking_ids.ids)]"

                           context="{'default_sale_order_id': active_id}">

                        <tree>

                            <field name="name"/>

                            <field name="weight" sum="Total weight"/>

                            <field name="picking_id"/>

                        </tree>

                    </field>
