I am trying out Odoo's community version, and when trying to modify a part of it, I have run into an issue that I am unable to solve. I am trying to add a custom field to the quotation in form view, which I have done successfully, but when trying to show that field in the tree view as its own separate column, it simply does not show up. I will add my custom sale_order_view.xml file below.
sale.order.form.inherit
sale.order
sale.order.tree.inherit
sale.order
I have tried to do "inside" "//tree" in xpath as well and neither works.
