the way the OpenERP rep instructed me to add new fields to forms is not working. I have added a field:

Field Name: x_username
Field Label: Outside Salesperson

Type: Custom Field
Model: Partner
In Modules: Null

Field Type: many2one
Object Relation: res.users
Relation Field: Null
Selection Options: Null
Domain: []
Serialization Field: Null
On Delete: Set NULL

Required: Null
Readonly: Null
Searchable: Not Searchable
Translatable: Null

No I am trying to add a view:

View Name: Outside Salesperson
View Type: Tree <--Won't let me edit to form'
Object: res.partner
Sequence: 16
Inherited View: res.partner.form
All other fields : Null

Architecture:
<?xml version="1.0"?>
<field name="ref" position="before">
<field name="x_username"></field>
</field>

When I try to save, it shows "Loading" for about 10 minutes and then returns the XMLHTTPREQUESTERROR.

I have tried even duplicating the normal res.partner.form view and editing it since it is already a form. Once I duplicate, if I try to edit the new res.partner.form, it will show loading for 10 minutes and then return the XML error. If I try to delete, it shows loading for 10 minutes and then returns the XML error. Now I have multiple copies of res.partner.form that I can't edit, delete, or otherwise get rid of and I can't add new views.

What gives?
