Hi everybody,

I'm trying to inherit sale.order QWEB template but it returns me always the same type of error whatever the template I inherit.

Here is my code in views/report_view.xml:

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data>

        <report
            id="adquat_chambon_report"
            string="Devis/Commande - Chambon"
            model="sale.order"
            report_type="qweb-pdf"
            name="adquat_report_changes.report_quotation_chambon"
            file="adquat_report_changes.report_quotation_chambon"
        />

        <template id="report_quotation_chambon" inherit_id="sale.report_saleorder_document">
            <xpath expr="//div[@class='page']" position="after">
                <p>TEST</p>
            </xpath>
        </template>

    </data>

</odoo>

And here is the error returned:

Odoo Server Error

The report works perfectly when I don't inherit templates but when I do it, it gives me errors.

Thanks for your help.
