I am creating auto-synchronizing collection, and for that I need
references to the same instance. If I do for example:
invoice.lineItems.Add(item);
item.invoice = invoice;
I would not have this issue, but since I "must" have auto-synch
collection, I need to get the reference to the proxy. Unfortunatelly,
in this code
collection.Owner is not a proxy, but original proxied object. I can
get around that if collection fetched has at least one member, because
I can look up inverse property in the item, but if there are no items
in the collection, I get above mentioned problem.
public void OnInitializeCollection(InitializeCollectionEvent @event)
{
IPersistentCollection collection = @event.Collection;
ISessionImplementor source = @event.Session;
CollectionEntry ce =
source.PersistenceContext.GetCollectionEntry(collection);
bool wasInitialized = collection.WasInitialized;
defaultListener.OnInitializeCollection(@event);
if (!wasInitialized)
{
string role = ce.LoadedPersister.Role;
string propertyName = role.Substring(role.LastIndexOf
(".") + 1);
PropertyInfo pi = collection.Owner.GetType
().GetProperty(propertyName);
