I'm trying to follow the instructions here however I think perhaps it's a different version. Using v7, I need to create some fields on the res.partner form and use them in the group by menu.

Already I have <?xml version="1.0"?><field name="ref" position="after"> <field name="x_user.id"> </field></field> which works just fine by itself, but adding the group by instructions on the linked question does not work.

So how do I add a group by to the code I have?

EDIT: So I've tried copying some of the existing views but I keep getting an error. Since the field I'm adding to the group by is essentially a copy of the Salesperson (user_id) field, I copied that view (res.partner.select) and saved it as res.partner.select2. Now I inherit the original res.partner.select and added:

<?xml version="1.0"?>
<search string="Search Partner">
                   <group expand="0" string="Group By...">
                       <filter string="Outside Salesperson" icon="terp-personal" domain="[]" context="{'group_by' : 'x_user_id'}"/>
                   </group>
               </search>

This apparently works to add the "Outside Salesperson" to the group by filter. However, when I try to acutally use that, I get an error:

Even when I edit the original res.partner.select do I get the same error. As in:
