I have create a new class using inherited by delegation of res.partner and created a new view for this class. I'm able to view my records in the new view, however when I try to create a child agent (child_ids is in res.partner) a view for res.partner is shown an a res.partner row is created with no custom.agent row. How can I force the view for a custom.agent?

Thanks Steve

class custom_agent(Model):
    _inherits = {
        'res.partner': 'partner_id',
    }    
    _name    = "custom.agent"
    _columns = {
        'commission_rate' : fields.float("Commission Rate"),
    }

Stripped down view

        <record id="view_custom_agent_form" model="ir.ui.view">
            <field name="name">custom.agent.form</field>
            <field name="model">custom.agent</field>
            <field eval="1" name="priority"/>
            <field name="arch" type="xml">
                <form string="Agent" version="7.0">
                <sheet>
                    <notebook colspan="4">
                        <page string="Contacts">
                            <field name="child_ids">
                            </field>
                        </page>
                    </notebook>
                </sheet>
                </form>
            </field>
        </record>
