Question

I have the following class

public class Room
{
  public virtual Guid Id { get; set }
  public virtual string Name { get; set }
  public virtual Guid LocId { get; set }
  public virtual Location Loc { get; set; }
}

I start transaction and call Session.Save for a new entity and it writes it to the database correctly, but if I immediately call GetList() the list is returned with the Loc property assigned for all entities except for the new entity, but if I set the Loc before calling Save it is assigned for the new entity. Flush() does not solve the problem. What am I missing, I would prefer not to get the Location to set it.

Answer 1

Mapping both Loc and LocId is an incorrect usage of NHibernate.

Use room.Location = session.Load<Location>(locId) to assign the Location.
