> In 6 different places in the AggregateResult test, a query is issued against
> FullTimeEmployee and returns an aggregate on "manager.salary". However, the
> "manager" field is of type Employee, and the "salary" field is only defined
> in the FullTimeEmployee subclass of Employee, thus rendering the aggregate
> statement invalid.
> The solution is to replace all instances of "manager.salary" with a clause
> that casts "manager" down to "FullTimeEmployee". E.g.:
> "(((FullTimeEmployee)manager).salary)"
