I'm trying to list all the products from a parent category, even if they're in a subcategory. Same as asked here: https://www.odoo.com/forum/help-1/question/list-products-in-all-subcategories-10874
I still can't make that work. But on one of my trial-error, I found out that deleting all the .xml files from /Server/server/openerp/addons/product/ has absolutely no effect. I restarted the service few times but the forms keeps working as usual and also the search functions and filters.
I spent all day trying to add a new filter when the problem seems to be that the service is not loading the xml files from where I thought. Why is that?
