Default Customer Tax Rule value disappears when it is saved
I replicated this bug in https://demo6.2.tryton.org/: (For the test, i will use the companies "Michael Scott Paper Company" and "Dunder Mifflin inc")
- I'm going to start form the company "Michael Scott Paper Company":
- Go to Financial -> Configuration -> Configuration
- Create a "Default Customer Tax Rule", in this case Tax Test "Michael Scott Paper Company"
- Do the same for the company "Dunder Mifflin inc"
- Return to "Michael Scott Paper Company"
- Create a party, for the test, i named it "Party Test"
- In the same party, go to the Accounting page
- Add a value in "Account Receivable" field
- The field "Customer Tax Rule" must have a value (from the default field in Financial configuration)
- Save
- Go to the company "Dunder Mifflin inc"
- Go to the same party we created in the "Michael Scott Paper Company" company
- If we go again to Accounting Page, the only field with value will be the "Customer Tax Rule" (this field will have the default value from the "Dunder Mifflin inc" Financial configuration)
- If we add a value to the "Account Receivable" and save, the value from "Customer Tax Rule" will disappear
I also replicated this bug in a local Tryton with the party and account modules installed (and its requirements)
