I've got a piece of code that adds Article2Storage entities. In the finest logging mode Eclipselink correctly has one persist call in the log.

[EL Finest]: 2012-04-26 10:28:07.708--UnitOfWork(21324714)--Thread(Thread[SwingWorker-pool-1-thread-1,5,main])--PERSIST operation called on: nl.reinders.bm.Article2Storage@12882ad&Oidnr=null.

Then upon commit out of the blue an insert on Batchtype is executed, which results in an exception on the primary key (since it naturally already exist):

I have no clue why that insert is executed. There are no Cascading persists defined, only some removes on certain activities.

Small addendum: I'm using Eclipselink 2.3.3-M1

And this is the problem code in the Standassign class:

public void createStorage()
{
// check to see if there already is a storage
String lStorageId = getStandversion().getStand().getStandid() + "/" + getCode();
Storage lStorage = Storage.findByDescription(lStorageId);
if (lStorage == null)
{
// add storage location
lStorage = new Storage();
lStorage.setDescription(lStorageId);
EntityManagerFinder.find().persist(lStorage);
}
else
{
// empty the storage
lStorage.removeAllArticle2Storage();
}

// set batchtype
lStorage.setBatchtype( getBatchtype() );

// fill storage with article
Article2Storage lArticle2Storage = new Article2Storage(getArticle(), lStorage);
EntityManagerFinder.find().persist(lArticle2Storage);
}

The "setBatchtype" is causing the insert.

But introduced another problem. By now I'm on M18, but I keep getting this exception:

java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager:

On "my side" of the fence, this is the line where the exception is generated:

Query lQuery = lEntityManager.createQuery(lJql);

I've placed a breakpoint in the visit method at ExpressionBuilderVisitor.java:2198, and indeed the second time it gets there, the instance field stateFieldPathExpression is null.
However, if I try to create a small test case, there is no problem.

String lJql = "select e_0 from Sellexpect e_0 where e_0.iSellexpectnr IN (select e_1.iSellexpectnr from Sellexpectline e_1 where e_1.iStandversionnr IN (select e_2.iStandversionnr from Standversion e_2 where e_2.iStandnr IN (select e_3.iStandnr from Stand e_3 where lower(e_3.iStandid) like :e_3_iStandid)))";
Query lQuery = lEntityManager.createQuery(lJql);
lQuery.setParameter("e_3_iStandid", "a1");
System.out.println( lQuery.getResultList() );

The srrange thing is, in the small test case, the visit method (ExpressionBuilderVisitor.java:2198) never is executed. The breakpoint is not triggered. How can this be?

I've binary searched when the query problem was introduced, and it has happened in the M17.1 build.

initial problem gone query runs ok
2.3.3-M1 no yes
2.4.0-M9 yes yes
2.4.0-M14 yes yes
2.4.0-M16 yes yes
2.4.0-M17.1 yes no
2.4.0-M17.2 yes no
2.4.0-M18 yes no

I've settled on M16 for now.

Please log a bug for the issue. Can you also try the latest 2.4 nightly build?

The nightly build will have to wait until the next time I'm working at the project.
