Concatenated primary keys (multiple columns can make up one primary key, e.g. a year number and an identifier for each season) are not supported by functions like MY_Model->as_dropdown(...)->get_all().
I would suggest making it possible to set $primary_key in extended classes either as string or array of strings.
