django-oscar validation error: attribute cannot be blank

Question

Im using the latest django-oscar from the master branch.

I've been tryin to understand how to use oscar, please help me with the problem below.

Using the admin page, first, I add the following Product Attribute

Product class: Base Card 
Name: Card Type 
Type: Option  
Option Group: 'Card Type' 
Required: checked

Then I tried adding a new Product with the product class Base Card. Under the Product Attribute Values section, I chose Card Type for the attribute, but no matter what values I inserted under e.g Value Option, text or Integer, I keep receiving the validation error below. Any idea why?

ValidationError at /admin/catalogue/product/add/
[u'cardtype attribute cannot be blank']

I'm afraid I'm not able to recreate your issue.

Did you definitely add options to your Card Type option group?
