Hello,

I've created my own module and I want to add attributes to a tree present in my view.

I've create this inherit views but I've got a problem with the addition of attributes for my tree.

This my code for change my parent form view:

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

        <field name="name">hide.create.register.tree</field>

        <field name="model">training.actions</field>

        <field name="inherit_id" ref="x_training.training_actions_form"/>

        <field name="type">form</field>

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

            <xpath expr="//field[@name='registred']/tree" position="attributes">

                <attribute name="create">False</attribute>

            </xpath>

            <xpath expr="//field[@name='blocking_registrations']" position="after">

                <field name="max_trained"/>

            </xpath>

        </field>

    </record>
        

When I go to my module and I click on the button "Create" nothing appends.

If I remove this part of my code :

<xpath expr="//field[@name='registred']/tree" position="attributes">

                <attribute name="create">False</attribute>

            </xpath>

What's wrong ?

Thanks for your help.

Regards
