And you can map it to the same class as the Product entity.

I cannot do the cleanup with raw rows, I do need real EOs. How can I override that model qualifier? When fetching raw rows I do get the data but I was not able to convert the dictionaries to EOs. The ID attribute is in the dictionary (which is the PK) but I get an IllegalArgumentException telling me "does not contain primary key information for entity Product"
