Very ordinary.
An abstract entity with three concrete subclasses implemented as a single MySql table.
I don't really need the PK, but when I try to save a new instance, no PK is generated (or at least, returned to the EODatabaseContext) and it throws an exception.
Any advice would be most appreciated.
