DataMapper ORM v1.8.2

I found the problem! Files were exactly the same so it was not that.

In the other site I used "bestsellers"-addon, which had this in the model(non-datamapper):

Code:

$this->db->select("COUNT(product_id) pr_count,product_id",false)->order_by('pr_count','DESC')->limit($limit)->group_by('product_id');

The earlier query worked for the other site as this little line has the "false" set as second parameter in the select method and from this query on, the rest of the queries are affected and are without(or are MOSTLY without) identifiers.

Maybe time to upgrade CI(and DM) for our eCommerce maybe?
