Hi,

I created a hierarchical tree which work :

    <record id="view_res_partner_tree_hierarchy_tis" model="ir.ui.view">

        <field name="name">view_res_partner_tree_hierarchy_tis</field>

        <field name="model">res.partner</field>

        <field name="field_parent">child_ids</field>

        <field name="arch" type="xml">

            <tree string="Sous contacts">

                <field name="name"/>

                <field name="type"/>

                <field name="parent_id" invisible="1"/>

            </tree>

        </field>

    </record>

Now, I'd like to display it as a sub-view into res_partner view-form :

I succeed to display the tree but it seems to "forget" the "field_parent" field :

    <record id="view_res_partner_contacts_form_tis2" model="ir.ui.view">

        <field name="name">view_res_partner_contacts_form_tis2</field>

        <field name="model">res.partner</field>

        <field name="inherit_id" ref="base.view_partner_form"/>

        <field name="arch" type="xml">

            <xpath expr='//field[@name="child_ids"]' position='replace'>

                <field name="child_ids" nolabel="1"

                    context="{'tree_view_ref':'mymodule.view_res_partner_tree_hierarchy_tis'}"/>

            </xpath>

        </field>

    </record>

(the views are based on standard res.partner object with its fields parent_id and child_ids)

Any help would be very appreciated !
