InsertOnSubmit Null Ref Exception on Linq to SQL DataContext EntitySet RRS feed

  • Question

  • I’m getting a null reference exception on a Linq to SQL foreign key EntitySet when trying to add a new entity.  The problem goes away when I comment out the EntitySet code (see below).  I don’t see any AssociationAttribute to allow this entirely normal situation.  What am I doing wrong?

    Thanks.  Steve

    // Child Entity Relationship
            private EntitySet<BBDetail> _BBDetails;
            [Association(Storage = "_BBDetails", OtherKey = "BBName")]
            public EntitySet<BBDetail> BBDetails
                {
                get { return this._BBDetails; }
                set { this._BBDetails.Assign(value); }
                }
