When creating a new product, if 'print vals' is used, the following is displayed:
{'product_tmpl_id': 90, 'message_follower_ids': [[4, 3]], 'attribute_value_ids': [(6, 0, [])]}
What is 'attribute_value_ids'?
I miss 'ean13' populated field that is later inserted into the database, how can I recover it?
