I have a parent-childs relation as described under:
public class Parent {
...
IList<Child> _childs = new List<Child>();
public virtual IEnumerable<Child> Childs {
get { return _childs.AsEnumerable<Documento>(); }
}
...
}
The related mapping is bidirectional:
class ParentMap
: ClassMapping<Parent > {
...
Bag(x => x.Childs, cm => {
cm.Inverse(true);
cm.Access(Accessor.NoSetter);
cm.Lazy(CollectionLazy.Lazy);
cm.Key(key => {
key.Column(map => map.Name("idproductcard"));
key.NotNullable(true);
key.OnDelete(OnDeleteAction.Cascade);
});
cm.OrderBy("absoluteposition asc");
cm.Cascade(Cascade.All | Cascade.DeleteOrphans);
}, m =>
{
m.OneToMany(otm => otm.Class(typeof(Child)));
});
...
}
class ChildMap
: ClassMapping<Child> {
...
ManyToOne<Parent>("Owner", map => map.Column("idproductcard"));
...
}
The idproductCard column in Child table isn't nullable.
The problem is that all works fine excepts for deletion: when I perform
a deletion, the childs data arent'deleted from db.
If I change db column from not-nullable to nullable, also deletion works
fine... in my real case I can't change this column due to legacy db.
Why I can't removes child records? Maybe because the column isn't
nullable and NH can't orphaned the records? Then key.NotNullable(true)
in the mapping is skipped?
I need to invoke manually deletion of this childs collection?
I'm still on 4.0.0.4000.
Thanks in advance.
