onchange return domain for one2many product ID Field

def onchange_partner_id(self, cr, uid, ids, part, context=None):
        res = super(sale_order, self).onchange_partner_id(cr, uid, ids, part, context=context)
       res['value'].update({'order_line': []})
       if part:
            product_obj = self.pool.get('product.product')
            matching_cust_ids = product_obj.search(cr, uid, [('x_cust_name','=',part)])
            res['value'].update({'custproduct_id': matching_cust_ids})
            domain = {'domain':{'order_line.product_id': [('order_line.id', '=', matching_cust_ids)]}}
            res['value']['order_line'].append(domain)
        return res

Issue: The above code return domain for one2many table product Field is not working.

For more background, what we were trying to do earlier (https://www.odoo.com/forum/help-1/question/limiting-customers-to-specific-products-58972) is link a customer and a product using a field on many2one field on the product page - 'x_cust_name': fields.many2one('res.partner', 'Customer', store=True). Ideally the module would only display the products that have the 'x_cust_name" equal to the name of the customer on the Sales Order.

Prakash - Janeesh's solution below worked! I think we were seriously overthinking things. Thanks again for your help, I really appreciate it.

If field_id is a many2one field to partner, then you can simply give domain in xml for product_id field. Domain should be domain="[('field', '=', parent.partner_id)]"

Ah of course it is way simpler than we were trying to make it. This worked perfectly using 'edit form view' from dev mode, but I am having trouble figuring out how to declare the xpath in my module. I am adding an answer with my code - if you could take a look I would really appreciate it.

Actually, scratch that - I figured it out. Thanks for the help!!

Janeesh - here is my attempt to implement your solution in a module. The domain isn't showing up for me right now, and I think it is because of my xpath declaration. Could someone help me figure out how to declare this domain correctly? Thanks!

EDIT: For anyone wondering the solution here, I think it had to do with the fact that the 'field' tag I was looking for was embedded past another field tag. The xpath that ended up working for me was:

<xpath expr="//field[@name='order_line']/tree/field[@name='product_id']"

which actually could be shortened to

xpath expr="//tree/field[@name='product_id']"

Here is my original (not functional) code.

  <record id="view_quotation_tree" model="ir.ui.view">

<field name="name">sale.order.form</field>

<field name="model">sale.order</field>

<field name="inherit_id" ref="sale.view_order_form"/>

<field name="arch" type="xml">

   <xpath expr="//field[@name='product_id']" position="replace">

<field name="product_id" context="{'partner_id':parent.partner_id, 'quantity':product_uom_qty, 'pricelist':parent.pricelist_id, 'shop':parent.shop_id, 'uom':product_uom}" groups="base.group_user" on_change="product_id_change(parent.pricelist_id, product_id, product_uom_qty, product_uom, product_uos_qty, product_uos, name, parent.partner_id, False, True, parent.date_order, False, parent.fiscal_position, False, context)" domain="[('x_cust_name', '=', parent.partner_id)]"/>

   </xpath>

</field>

   </record>
