Hi,

I'm using v7 and I'm creating a custom module to change the product.product.tree view.
I want to add "loc_rack", loc_row", "loc_case" columns to it.
Here is my xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
  <data>
    <record model="ir.ui.view" id="product_tree_locations">
        <field name="name">product.product.tree</field>
        <field name="model">product.product</field>
        <field name="inherit_id" ref="product.product_product_tree_view" />
        <field name="arch" type="xml">
           <xpath expr="/tree/field[@name='state']" position="before">
                <field name="loc_rack" />
                <field name="loc_row" />
                <field name="loc_case" />
            </xpath>
        </field>
    </record>
  </data>
</openerp>

This actually works, but it fails miserably when I want to either upgrade or do a: --update=all
This is the error:

 ERROR moduletest openerp.osv.orm: Can't find field 'loc_row' in the following view parts composing the view of object model 'product.product': * product.product.tree

except_osv: ('ValidateError', u'Error occurred while validating the field(s) arch: Invalid XML for View Architecture!')

Is it because the loc_ fields are from product.template ???  In that case, how do i get these on product.product.tree ??

Bole: I get a recursion error on this:

class product_product(orm.Model):
    _inherit = 'product.product'
    _columns = {
        'loc_rack': fields.related('product_tmpl_id','loc_rack',type="char", string="Rack"),
        'loc_row': fields.related('product_tmpl_id','loc_row',type="char", string="Row"),
        'loc_case': fields.related('product_tmpl_id','loc_case',type="char", string="Case"),
    }
product_product()

Should I use   'new_loc_rack': fields.related(...  and use   <field name="new_loc_rack"/> in the xml ?
