The method merge from EntityManager causes a duplication of child entity's.

1").getSingleResult();
Child c = new Child();
c.setFather(f);
f.getChildList().add(c);
em.getTransaction().begin();
em.merge(f);
em.getTransaction().commit();
The execution of BugTest Class causes tow insert's on table "child".
If you change the fetch mode to EAGER (into Father class) the problem not occurs.
I make the same test with Toplink, and it make a unique insert, normal.

This is a Eclipse project with a sample code using MySQL database. Please let me know if
you have any doubts or problems.
The Console shows the Childs class inserted twice. But I have only inserted one Child.
Starting the bug method...
Hibernate: select father0_.id as id5_, father0_.s_nome as s2_5_ from father father0_
Hibernate: insert into child (id_father, s_nome, Id) values (?, ?, ?)
Hibernate: insert into child (id_father, s_nome, Id) values (?, ?, ?)
Finished the bug method...

-----------------------------
Hi,
I've exactly the same problem and I've found a - very bad - solution :
cascade = { CascadeType.MERGE, CascadeType.REMOVE, CascadeType.REFRESH,
CascadeType.PERSIST }
instead of :
cascade={CascadeType.ALL}
correct the problem. This is surprising because it should done the same thing ...

This works fine when a Set is used as the child collection type. Not only are there not
two resulting children, only one insert happens.

Yup, this seems pretty easily reproducable. I'm getting this to happen too. Both the
following seem to fix it
- changing from CascadeType ALL to just the relevant one
- And specifying fetchmode as eager

Mike Ressler commented on HHH-3332:
-----------------------------------
I ran into this using version 3.3.1.
The workaround I'm using at the moment is to add the child to the beginning of the
list. So the code in the example would be:
Child c = new Child();
c.setFather(f);
f.getChildList().add(0, c);
This is working for me at the moment. I'm surprised this bug has been open for so
long.

The method merge from EntityManager causes a duplication of child entity's.
class Father:
@OneToMany(mappedBy = "father", cascade={CascadeType.ALL},
fetch=FetchType.LAZY)
private List<Child> childList;
class Child:
@ManyToOne @JoinColumn(name = "ID_FATHER")
private Father father;
class BugTest
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("JpaTestHB");
EntityManager em = emf.createEntityManager();
Father f = (Father) em.createQuery("SELECT f FROM Father f WHERE f.id =
1").getSingleResult();
Child c = new Child();
c.setFather(f);
f.getChildList().add(c);
em.getTransaction().begin();
em.merge(f);
em.getTransaction().commit();
The execution of BugTest Class causes tow insert's on table "child".
If you change the fetch mode to EAGER (into Father class) the problem not occurs.
I make the same test with Toplink, and it make a unique insert, normal.

Hi,
This is my use case:
public class Round {
...
@OneToMany(fetch = FetchType.LAZY, mappedBy = "route")
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
org.hibernate.annotations.CascadeType.MERGE,
org.hibernate.annotations.CascadeType.REMOVE
})
@org.hibernate.annotations.Fetch(value =
org.hibernate.annotations.FetchMode.SUBSELECT)
public List<SubRound> getSubRoutes() {
return subRounds;
}
@Transient
public void addSubRoute(SubRound sr) {
if (sr != null) {
sr.setRoute(this);
getSubRoutes().add(sr);
}
}
...
}
public class SubRound {
...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "route_id")
public Round getRoute() {
return route;
}
...
}
Round r1 = new Round();
r1 = getHibernateTemplate().merge(r1);
SubRound sr1 = new SubRound();
r1.addSubRoute(sr1);
getHibernateTemplate().merge(sr1);
There will be two SubRound(s) rows in the database.

------------------------------------
This replicates if you save the Child and the Parent also has a reference to it, and not
when saving the Parent.
See my previous example, when I save sr1, you get 2 SubRound rows, if instead I save r1, I
only get one SubRound.
I hope this example helps.

Vlad Mihalcea commented on HHH-3332:
------------------------------------
With both 3.2.6.ga and 3.2.7.ga when I save the Child, there will be two rows in the
database, but when I save the Parent there is just one Child row in the database. I know
that the first example was related to saving the Parent, but with my settings
(@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.REMOVE
})) it seems that I have the issue only when I save the Child directly.
I checked it in my project, but I think you can replicate it also with the TestCase Fabio
Mattavelli has attached to this issue.

Trond Isaksen commented on HHH-3332:
------------------------------------
I believe the problem is that when merging from a child C1 to a parent P, the cascade is
done BEFORE the save, which means that the parent will actually do a cascade back to the
child C1 first, which will then be inserted. After the parent has been processed, the
first C1 merge()-call will insert the child again. I believe that exchanging the
DefaultMergeEventListener with the following fixes the problem:
public class ModifiedIdTransferringMergeEventListener extends DefaultMergeEventListener {
private static final long serialVersionUID = 1L;
static ThreadLocal<IdentitySet> transientObjects = new
ThreadLocal<IdentitySet>();
/**
* Hibernate 3.1 implementation of ID transferral.
*/
protected void entityIsTransient(MergeEvent event, Map copyCache) {
boolean topLevelInvocation = transientObjects.get() == null;
if (topLevelInvocation) {
transientObjects.set(new IdentitySet());
}
if (transientObjects.get().contains(event.getEntity()))
return;
transientObjects.get().add(event.getEntity());
super.entityIsTransient(event, copyCache);
//Start IdUpdating
SessionImplementor session = event.getSession();
EntityPersister persister = session.getEntityPersister(event.getEntityName(),
event.getEntity());
// Extract id from merged copy (which is currently registered with Session).
Serializable id = persister.getIdentifier(event.getResult(),
session.getEntityMode());
// Set id on original object (which remains detached).
persister.setIdentifier(event.getOriginal(), id, session.getEntityMode());
//End IdUpdating
if (topLevelInvocation) {
transientObjects.get().clear();
transientObjects.set(null);
}
}
}
The transientObject threadlocal just remembers the objects that are going to be inserted,
and stop cascading from reaching them again. A better implementation would obviously be to
send the map with "inflight" objects as a parameter instead of using a
threadlocal. Please note that this implementation also contains the code from the
IdUpdatingMergeEventListener(Spring), which updates the id of merging objects as the merge
takes place. To me that is the only reasonable approach...but this can be easily changed
by removing those lines.
However, I am too concerned about potential side-effects to actually put this into
production, which means we are stuck with an approach with tedious and painful object
rearranging and decoupling-operations. Would be nice to have a comment from the official
team. :-)

Could someone please try the attached test case with 3.5.2 to see if it is still a problem

with other types of collections in 3.5.2?

Trond Isaksen commented on HHH-3332:
------------------------------------
Yes, we are just using regular List one-to-many/many-to-one-relations with cascade merge
both ways. If a merge-call is done on the parent, everything works fine. If a merge is
called on the child, the merge is cascaded to the parent and then back to the child again,
which creates one extra insert.
I've also tried with the latest (3.5.2?) version, which has the same problem.

1").getSingleResult();
Child c = new Child();
c.setFather(f);
f.getChildList().add(c);
em.getTransaction().begin();
em.merge(f);
em.getTransaction().commit();
The execution of BugTest Class causes tow insert's on table "child".
If you change the fetch mode to EAGER (into Father class) the problem not occurs.
I make the same test with Toplink, and it make a unique insert, normal.

Gail Badner resolved HHH-3332.
------------------------------
Resolution: Cannot Reproduce
Tron, your pom.xml uses core 3.3.1 and annotations 3.4.0.GA. When I updated both to use
3.5.4-SNAPSHOT, your tests pass.

-----------------------------------
I just downloaded hibernate-3.5.5-Final to see if this was resolved The issue still
exists for me. Anyone else following this bug having similar problems? I'll try to
come up with a failing test case for this issue.
