Create a new entity with new qualifier. InvisibleProduct. Fetch and delete.

Folks,
I have an entity Product with an attribute isVisible. Throughout my application I only work with products that are visible. So I have specified a qualifier visible='Y' right in the model. This qualifier is automatically AND-added to each and every query agains Product. Fine, I am happy with this.
Now the customer needs an automatic cleanup function. This function must fetch products that are not visible. Cleanup requires more than just deletion from the database. 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"
This is the code I use (maybe there is a problem there)
NSMutableArray<Product> products =
new NSMutableArray<Product>();
NSArray<NSDictionary<String, Object>> rawRows = EOUtilities.rawRowsForSQL( ec, "ec2", "select * from PRODUCT where visible = 'N' ", null);
for (NSDictionary row : rawRows) {
Product prod = (Product) EOUtilities.objectFromRawRow( ec, Product.ENTITY_NAME, row );
products.addObject( prod );
}
Thanks for your help
