You also must take some things in consideration:
- Relations must be entities or simple collections of entities
(IListT, IEnumerableT), not sets (ISetT, HashSetT) or maps
(IDictionary, IDictionaryK, V, HashTable);
- The ID property must be called either ID, or end with ID, for
example,
@Krzysztof:
Shouldn't you be calling the base class' implementation?
public class MySaveOrUpdateEventListener:
DefaultSaveOrUpdateEventListener
{
public override void OnSaveOrUpdate(SaveOrUpdateEvent @event)
{
//do something with the entity
base.OnSaveOrUpdate(@event);
or simple collections of entities.But
Category is an entity, what else can it be? I also tried changing from
ICollection to IList, but still the same error on many side of the
relation.

The error is related to having a proxy (Castle) instead
WCF Data Services supports projections (server-side, not client-side,
this you can always do with LINQ to Objects), but you have to enable
them:
public static void InitializeService(DataServiceConfiguration config)
{
config.DataServiceBehavior.MaxProtocolVersion =
Most likely because you have a null column in the database mapped to a
non-nullable property. NHibernate detects that the current value is
different than the loaded value (null) and tries to save the entity.

Is your entity marked as lazy?
If not, the only thing that can be lazy loaded (or proxied, if you
prefer) is one to many collections.

Yeah, it does load the reference if you set lazy=no-proxy although the

Hi,
I am having this problem:
- I load a User entity from the DB using session.GetT();
- It loads an additional collection UserGroups containing only one
entity;
- I have an event listener for the SaveOrUpdate event:
cfg.EventListeners.SaveOrUpdateEventListeners =
Forgot to tell: I am using HiLo for ids and, of course, I am not
changing anything on any of the loaded entities. No second level cache
either.
