[Tinyerp-users] properties: cannot attach external properties

[forum-user]

I created a new module and overrode res.partner so that I could attach an 
external property from my new module to it.  

py:

class res_partner(osv.osv):
    _name = 'res.partner'
    _inherit = 'res.partner'
    _columns = {
        'property_mynewobject_somefield': fields.property(
        'mynewobject.somefield',
        type='many2one',
        relation='mynewobject.somefield',
        string="Some Field",
        method=True,
        view_load=True,
        group_name="My Properties"),
    }
res_partner()


xml:

<record>
    <field>property_mynewobject_somefield</field>
    <field>
    <field>mynewobject.somefield</field>
</record>



The new module installs but displays this error:

recent call last):

    names = dict(obj.name_get(cr, uid, filter(None, res.values()), context))
AttributeError: 'NoneType' object has no attribute 'name_get'




and the new property appears on the Properties sidetab for the Partner however 
no property now receives its default
value and when you try to add/edit the new property you receive this error:

Exception: warning -- Object Error

Object mynewobject.somefield doesn't exist


I checked the ir_model_fields table and the entry is there for res.partner.

I followed the docs but this does not appear to work.
