Hi,

I'm trying to display lead data related to a partner.

But on module installation, I keep having the ValidateError saying Error occurred while validating the field(s) arch: Invalid XML for View Architecture!

I don't know why this is happening, cause I've double checked fields names, and compared my xml structure and content to other module xml view files.

I've also set dependencies to 'base','crm', in __openerp__.py

Does anyone see something wrong in my code below ?

Here is my piece of python code:

class res_partner(osv.osv):
    _inherit = 'res.partner'
    _columns = {
             'lead_ids': fields.one2many('crm.lead', 'partner_id', 'Leads'),
    }

And here my view:

<?xml version="1.0"?>
  <page string="Accounting" position="after" version="7.0">
  <page string="History" name="cap_history_tab">
    <!-- Customer Leads Group -->
    <group name="grp_leads_history" string="Leads History">
          <field name="lead_ids" colspan="4" nolabel="1">
            <tree string="Partner Leads" editable="false" create="false" delete="false">
              <field name="name" readonly="True"/>
              <field name="create_date" readonly="True"/>
              <field name="date_deadline" readonly="True"/>
              <field name="priority" readonly="True"/>
              <field name="planned_revenue" readonly="True"/>
              <field name="probability" readonly="True"/>
              <field name="state" readonly="True"/>
            </tree>
          </field>
        </group>
  </page>
</page>

Thank you for your help

Cheers
