getEntityName() throws org.hibernate.TransientObjectException: proxy was not associated
with the session
--------------------------------------------------------------------------------------------------------
Key: HHH-3230
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3230
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.2
Environment: Mac OS X, JDK 1.5
Reporter: Howard M. Lewis Ship
I'm retrieving an entity that contains a OneToMany relationship.
The master entity is retrieved, within a transaction, via
Session.get(Class,Serializable).
@Entity
public class MapUnitSurvey extends ActiveDO
{
@ManyToOne(fetch = FetchType.LAZY)
private VegetationType vegetationType;
}
@Entity
public class VegetationType extends AbstractEnum
{
}
ActiveDO and AbstractEnum are abstract base classes with @MappedSuperclass.
I retrieve the vegationType:
VegetationType type = survey.getVegetationType();
Then I need the type's entity name
String entityName = session.getEntityName(type);
This fails with the TransientObjectException.
Inspecting with the debugger, I see that type is a CGLIB-enhanced proxy, and that
there's a fully initialized bean in the target field of the proxy. I'll attach a
screenshot of some debugging data.
In summary; the entity was retrieved via a lazy fetch, appears the be correct, seems to be
in the session and yet the exception occurs.
I've tried to resolve this by re-fetching the object from the session, and a few other
tries, with no luck.

-------------------------------------------
It appears that converting the vegationType relationship from lazy to default (eager)
fixes the problem.

New subject: [Hibernate-JIRA] Commented: (HHH-3230) getEntityName() throws org.hibernate.TransientObjectException: proxy was not associated with the session

------------------------------------
Gail, the test succeeds if the exception is thrown, therefore is still an issue in
Hibernate 3.6.1-SNAPSHOT.
But I am realizing that it's a bit confusing, so this is the version of the test that
fails if the exception is thrown and succeeds if the exception isn´t thrown

Key: HHH-3230
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3230
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.2.2, 3.6.0
Environment: Mac OS X, JDK 1.5
Reporter: Howard M. Lewis Ship
Attachments: Debugging output from IDEA.jpg, NarrowingProxyTestCase.zip
I'm retrieving an entity that contains a OneToMany relationship.
The master entity is retrieved, within a transaction, via
Session.get(Class,Serializable).
@Entity
public class MapUnitSurvey extends ActiveDO
{
@ManyToOne(fetch = FetchType.LAZY)
private VegetationType vegetationType;
}
@Entity
public class VegetationType extends AbstractEnum
{
}
ActiveDO and AbstractEnum are abstract base classes with @MappedSuperclass.
I retrieve the vegationType:
VegetationType type = survey.getVegetationType();
Then I need the type's entity name
String entityName = session.getEntityName(type);
This fails with the TransientObjectException.
Inspecting with the debugger, I see that type is a CGLIB-enhanced proxy, and that
there's a fully initialized bean in the target field of the proxy. I'll attach a
screenshot of some debugging data.
In summary; the entity was retrieved via a lazy fetch, appears the be correct, seems to
be in the session and yet the exception occurs.
I've tried to resolve this by re-fetching the object from the session, and a few
other tries, with no luck.
