Hi, I'm trying to have default taxes set for Customer Taxes in the Product Template set to a new tax I created called "Tax Exempt". However I'm getting an error when changing the default ID value to my new ID value. Furthermore, it won't even let you change it back to the original ID without giving and error, see below.
Settings>Activate Developer Mode
taxes_id>Edit>Delete "" in the "Default value or action reference"
Save>Edit>Add the exact same  back in >Save
You will receive an error message "ValueError: Wrong value for product.template.taxes_id: "
How can this happen, it works with the value for ID before, but if you save and re-enter it, it has a problem. All I'm trying to do is have the default Customer Taxes be "Tax Exempt" which is ID "3". Therefore I would have assumed I could enter  in the Default Values and this would worked.
