Hello,

I have following field in sale.py

'product_id': fields.many2one('product.product', 'Product', domain=[('sale_ok', '=', True)], change_default=True, readonly=True, states={'draft': [('readonly', False)]}, ondelete='restrict'), 

Here my domain is domain=[('sale_ok', '=', True)]

Now I want to extent this domain like

<xpath expr="//field[@name='order_line']/form/group/group/field[@name='product_id']" position="attributes">
       <attribute name="domain">[('sale_ok','=',True),('my_new_field','=',True)]</attribute>
</xpath>  

But its not working.

I have another idea if I replace product_id with new field like

'product_id': fields.many2one('product.product', 'Product', domain=[('sale_ok', '=', True),('my_new_field','=',True)], change_default=True, readonly=True, states={'draft': [('readonly', False)]}, ondelete='restrict')
