Hello:
I was expecting the HasOne relationship that is part of my inheritance
mapping to not let me save a ProjectActivity unless it's Project
attribute exists in the db (Project is a mapped Entity also). Is there
an option I can use to enforce this?
Thanks!

Domain inheritance hierarchy
-------------------------------------------------
public abstract class Activity : Entity { ... }
public class ProjectActivity : Activity {
public virtual Project Project { get; private set; }
}
public class AccountActivity : Activity {
public virtual Account Account{ get; private set; }
}
Mapping
-----------------------
public class ActivityMap : IAutoMappingOverride<Activity>
{
public void Override(AutoMap<Activity> mapping)
{
..........
mapping.DiscriminateSubClassesOnColumn("ActivityType")
.SubClass<ProjectActivity>("P",
x => x.HasOne(y => y.Project)
.Cascade.None()
.FetchType.Join())
.SubClass<AccountActivity>("A",
x => x.HasOne(y => y.Account).Cascade.SaveUpdate
().FetchType.Join())
}
}
