I cannot seem to get the Fiscal Position Rule to work in v8. I installed the app "Account Fiscal Position Rule" and created a rule for:

Origin.Company: "My Company"

Shipping.Destination Country: "United States"

Shipping.Destination State: "California"

Fiscal Position: "FP_CA"

Use in: Sales Order, Invoices, Purchasing, Picking

I even tried adding a start date and an end date.

I then created a Sales Order with a ship to address in California, but the tax remained default.

On the Sales Order, if I click "Open: Customer" and assign Fiscal Position "FP_CA", then the sales tax changes to CA.

I was following this video, but it seems to be OpenERP v7: https://www.youtube.com/watch?v=_7Yip6zfZzw

Does anyone know if this actually works in v8 or some other way to accomplish it?

I want to do it via a rule so that I don't have to change every customer, and for customers ordering via eCommerce.
