@NotFound(action=NotFoundAction.IGNORE) results in EAGER loading for @ManyToOne(fetch =
FetchType.LAZY) field
-------------------------------------------------------------------------------------------------------------
Key: HHH-3917
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3917
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Reporter: Vlasov Igor
Hello
I try to use @org.hibernate.annotations.NotFound(action=NotFoundAction.IGNORE) annotation
to avoid of throwing an exception IN
@JoinColumn(name = "UR_ID", referencedColumnName = "UR_ID")
@ManyToOne(fetch = FetchType.LAZY)
@org.hibernate.annotations.NotFound(action=NotFoundAction.IGNORE)
@Basic(optional=true)
private UserRole role;
Then it results me to EAGER loading of this field.
Throw days of debuging i have found that:
1. @org.hibernate.annotations.NotFound results in:
isNullable()=true
for org.hibernate.type.ManyToOneType
2. in org.hibernate.impl.SessionImpl and method internalLoad i can see:
LoadEventListener.LoadType type = nullable ?
LoadEventListener.INTERNAL_LOAD_NULLABLE :
eager ? LoadEventListener.INTERNAL_LOAD_EAGER : LoadEventListener.INTERNAL_LOAD_LAZY;
Threrefore we have LoadEventListener.INTERNAL_LOAD_NULLABLE type of loading my relation.
!!!
and in class org.hibernate.event.LoadEventListener.INTERNAL_LOAD_NULLABLE I can see
setAllowProxyCreation(false) !!!!
3. in org.hibernate.event.def.DefaultLoadEventListener in line 218 there is a condition:
if ( options.isAllowProxyCreation() ) {
return createProxyIfNecessary( event, persister, keyToLoad, options, persistenceContext
);
} else {
return load(event, persister, keyToLoad, options);
}
In my case LoadEventListener.INTERNAL_LOAD_NULLABLE.isAllowProxyCreation() ==false !!
and it results in LOADING of Object !!!
Can we set LoadEventListener.INTERNAL_LOAD_NULLABLE.isAllowProxyCreation() to true ?
org.hibernate.event.LoadEventListener.INTERNAL_LOAD_NULLABLE = new
LoadType("INTERNAL_LOAD_NULLABLE")
.setAllowNulls(true)
.setAllowProxyCreation(false)
.setCheckDeleted(false)
.setNakedEntityReturned(false);

The method org.hibernate.event.def.DefaultLoadEventListener.load(...)
internaly call method of same class
protected Object loadFromDatasource(
final LoadEvent event,
final EntityPersister persister,
final EntityKey keyToLoad,
final LoadEventListener.LoadType options) {

}
In this method There is no any dependencies on parameter "final
LoadEventListener.LoadType options"
(in my case INTERNAL_LOAD_NULLABLE)

-----------------------------------
Perhaps this is due to the fact that you cannot proxy a null reference?
The missing object being referred to would not be null, because it would be a proxy
instance to an object which you don't know is missing or not, but then on access, when
it would be found to be missing, it would have to become null.
