Hi

I'm trying to show the 'History' tab on the partner Kanban view. To do that I created a new module with a *_view.xml file containing as follow:

<?xml version="1.0"?>
<openerp>
<data>
    <menuitem id="menu_config_captivea" name="Captivea"
        groups="base.group_no_one"
        parent="base.menu_base_config" sequence="55"/>

    <record id="view_history_partner_info_form1" model="ir.ui.view">
        <field name="name">res.partner.history.info.form</field>
        <field name="model">res.partner</field>
        <field name="inherit_id" ref="base.view_partner_form"/>
        <field name="priority">20</field>
        <field name="arch" type="xml">
            <xpath expr="//page[@name='page_history']" position="attributes">
                <attribute name="invisible">False</attribute>
            </xpath>
            <xpath expr="//page[@name='page_history']" position="inside">
                <group name="grp_cap_history_partner" string="Invoice History">
                  <field name="state" invisible="True" />
                  <field name="invoice_ids" editable="bottom">
                      <field name="name"/>
                    </tree>
                  </field>
                </group>
            </xpath>
        </field>
    </record>

</data>

</openerp>

I also created a *.py file into the module folder containing the inheritance of the class res_partner:

class res_partner(osv.osv):
_inherit = 'res.partner'
_columns = {
    'invoice_ids': fields.one2many('account.invoice', 'partner_id', 'Invoices'),
    'order_ids': fields.one2many('sale.order', 'partner_id', 'Invoices'),
}

When I go to a partner Kanban view, on the history Tab, I have nothing showed, even if I select a partner that has invoice. If I click on the expandable 'Description' row, I get the error

QWeb2 - template['ListView.row']: Runtime Error: Error: Unknown field state in domain [["state","not in",["draft"]]]

As I don't deal with state in the *view.xml file I don't understand how I come to this error.

Thanks for your help

Cheers
