Comment 14 for bug 1599634

IMO, if a template didn't include or filter on circ_type, then it's not providing enough information to disambiguate. Concatenating the id and type doesn't really help, because the user can choose to not include the id column as well. While we don't use them much in EG, multi-column primary keys (which id + type is, effectively) are perfectly valid.

In any case, though, we really do need to include the bare id, whether we provide a combined id/type column or not.
