Not getting NHibernate Cascade Delete Orphan working with Automapping

Question

Having tried several solutions to get NHibernate to delete orphan records. Given the following structure:

public class Parent {

    public virtual ICollection<Domain> Domains {get;set;}

}
public class Domain{

    public virtual Parent Parent {get;set;}
}

UPDATE: It had nothing to do with the setter. This caused something else to go wrong which was fixed. But the deletion of orphans still does not happen I have tried the following:

• Add an attribute on Domains (and on the Parent property of the Domain class) according to http://mookid.dk/oncode/archives/643

• Added Automapping like:

  AutoMap.Override<Parent>(map => { map.HasMany(x => x.Domains).Inverse().Cascade.All(); })
  AutoMap.Override<Parent>(map => { map.HasMany(x => x.Domains).Cascade.All(); })
  

Both caused the Domain records to be stored with Parent_Id = null.

Is there any good example on how to achieve this in combination with Automapping?

Answer 1

you do not have specified deleteOrphan

map.HasMany(x => x.Domains).Inverse().Cascade.AllDeleteOrphan()
