I may have spoken too soon.
Every Schedule HasOne associated Scheduler, AbstractScheduler,
extending into SeasonScheduler, TournamentScheduler, and so on.
In the Schedule mapping:
HasOne(x => x.Scheduler)
.PropertyRef(r => r.Schedule)
.Cascade.All();
Unless Fluent and/or NHibernate is having a problem with the
abstraction, I fail to see how it does not find the property Schedule
referring to the Scheduler's parent.
Another possibility, is PropertyRef necessary? Or use References in
the child on the other side of the HasOne (or HasMany)?
Thank ye...
