Hi,

I would like to create a new external layout to have the customer address on the same line as the company address for my sale order pdf report

I went to Settings > Technical > User Interface > Views and duplicated the external_layout_folder in order to personalize the layout through code, using a custom <t t-name="web.external_layout_folder_custom"> in this view.
Then, I call this template with <t t-call="web.external_layout_folder_custom"> in my pdf sale order report

But the field External ID is greyed out in my view external_layout_folder_custom and when I try to save my sale order pdf report, I have this error in odoo.sh logs

odoo.addons.base.models.ir_qweb.QWebException: Error while render the template

ValueError: External ID not found in the system: web.external_layout_folder_custom

I have created a new external identifier though Settings > Technical > Sequences & identifiers > External identifiers

Is it the right way to do it ?

I am on Odoo 18, running on Odoo.sh
