EntityHome.persist fails with @GeneratedValue

[dougorr]

I am using a simple Seam-Gen generated application. I want to change the @Id field in the model class to be auto-generated. I changed the annotation to read as follows:

@Id @GeneratedValue(strategy=GenerationType.AUTO)

When I run the application the EntityHome.persist throws an exception. Here is the stack trace:

Can anyone suggest the cause? What other changes do I need to make to support auto-generated ids?

[fhh]

If you want to update an entity use merge (not persist).

[dougorr]

This was not an update process. This exception was raised when I tried to Create a new instance of an entity using the Seam-Gen generated pages. The only change I made to the application was to annotate the Id of the class to use @GeneratedValue(strategy=GenerationType.AUTO).

[pmuir]

The exception is clear. You are passing an entity Hibernate knows about (i.e. is already persisted) to persist. You can't do that. You'll need to use a debugger to find out why.

Same problem here (but w/o EntityHome design pattern). I am seeing the following in the server.log before the exception. Occurs with or w/o using the TransactionalSeamPhaseListener in faces-config.xml. I am using SMPC with flushMode=MANUAL. This could be a programmer's error but I don't know why it states "mark transaction for rollback" when the persist() method is called on the EntityManager. There is no SQLException in the server.log.

SFSB:

for (int i = 0; i < 3; i++) {
 TblSecurityAuditNote note = getTblSecurityAuditNote(currentRowNum, i);
 if (note != null) {
 log.info("myNotes["+currentRowNum+"]["+i+"]: noteId = " + note.getNoteId() + " noteText = " + note.getNoteText());
 emICOMS.persist(note);
 }
 }

 emICOMS.flush();

[asookazian]

well I determined the root cause of the exception I was getting (org.hibernate.PersistentObjectException: detached entity passed to persist: com.cox.beans.entity.TblSecurityAuditNote). It was that I had a loop that was trying to persist an already perstisted/inserted JPA entity into the DB and Hibernate notices this and throws the exception before you get a primary key violation SQLException from DB.

So in my case it was a programmer's error. The fix was to set the already persisted entity to null in the array so in the code it will not exec the em.persiste(note) again.

I think that the wording of the hibernate exception could be more clear. I still don't understand exactly what it's trying to indicate literally (I now know it's saying you're trying to insert a record in the table which has an existing primary key value).
