So I'm trying to add an extra column in my customers list view. I created a new column for it called x_company and now I'm trying to get the field to appear on the screen.

This is what I currently got:

<record id="view_partner_tree_inherit" model="ir.ui.view"> 
<field name="name">res.partner.tree</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_tree"/>
<field name="arch" type="xml">
<tree string="Contacts">
<field name="x_company"/>
</tree>
</field> 
</record> 

Of course with the necessary tabs in place, as you can see I'm trying to add the column x_compay which is defined in a custom python file. I know the xpath determines the position of the field so I'm wondering if it has to be inside the tree tag or outside, and if what I'm doing is alright.

Thanks in advance
