hi

 In odoo 12, when we try to add additional fields to SO line, it is throwing an error.

This is happening only when there is a Quotation Template present with line items. 

It actually says field in not there in domain.

If we set a default quotation template (Template A with line items), it will show field qty_invoiced is not present in domain

If we set a default quotation template (Template B without line items) and if we try to change quotation template, it will show field product_updatable is not present in domain

I tried inheriting the view and adding additional fields as well as directly adding the sale module. Nothing seems to be working

Looks like this issue in the Odoo JS framework

Any suggestions how to fix this issue?
