Hi Anas, I have like in your example but it is not enough. I want to have chatter in Popup Form view.

Hello ,

Modify the Form View  :

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

    <field name="name">your.model.form</field>

    <field name="model">your.model</field>

    <field name="arch" type="xml">

        <form string="Your Model Form">

            <sheet>

                <group>

                    <!-- Your fields go here -->

                </group>

            </sheet>

            <chatter/>

        </form>

    </field>

</record>
