[hibernate-issues] [Hibernate-JIRA] Resolved: (EJB-236) EntityManager Exception when closing transaction (Fetch.LAZY) takes no affect

EntityManager Exception when closing transaction (Fetch.LAZY) takes no affect ----------------------------------------------------------------------------- Key: EJB-236 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-236 Project: Hibernate Entity Manager Type: Bug

Environment: EntityManager 3.2.0.cr3, Sybase Reporter: Meinolf Assignee: Emmanuel Bernard Priority: Critical Attachments: HibernateEntityManagerTest.java, Tras001.java, Tras001Home.java Hi gurus, I just played a little bit arround with the Hibernate Entity Manager and found a bug which is nearly similar to a already closed bug: http://opensource.atlassian.com/projects/hibernate/browse/EJB-221 I've done an updated of all jar files of the "fix version/s 3.2.0.cr3 but this didn't help. I'm using EntityManager and reading by id a Project object out of the database which has a number of oneToMany references within. All references are declared as Fetch.LAZY but using hibernates EntityManager does this not take into account. When committing the transaction I get an Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.arvato.hibernate.entities.Tras001.tras070 -> com.arvato.hibernate.entities.Tras070 without saving anything, I do just a simple read?! So we've two errors here, 1. Why are Fetch.LAZY things read by default (Affected: EntityManager with annotation configuration and xml configuration as well) 2. TransientObjectException (Affected: EntityManager with annotation configuration. XML configuration does not throw this but does a read of lazy objects) I'll attach the Domain Object and the test class to make some things more clear to you. Cheers Meinolf P.S: There is another bug I found a few days ago regarding a wrong binding order of parameters. Can you please take a look at http://forum.hibernate.org/viewtopic.php?t=965575 This happens only when using annotation configuration. (Affected: Session and EntityManager) Here's the full stack trace: javax.persistence.RollbackException: Error while commiting the transaction at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:63) at com.arvato.hibernate.entities.test.HibernateEntityManagerTest.load(HibernateEntityManagerTest.java:71) at com.arvato.hibernate.entities.test.HibernateEntityManagerTest.main(HibernateEntityManagerTest.java:31) Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.arvato.hibernate.entities.Tras001.tras070 -> com.arvato.hibernate.entities.Tras070 at org.hibernate.engine.CascadingAction$9.noCascade(CascadingAction.java:350) at org.hibernate.engine.Cascade.cascade(Cascade.java:139) at org.hibernate.event.def.AbstractFlushingEventListener.cascadeOnFlush(AbstractFlushingEventListener.java:130) at org.hibernate.event.def.AbstractFlushingEventListener.prepareEntityFlushes(AbstractFlushingEventListener.java:121) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:65) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:53) ... 2 more Exception in thread "main" java.lang.IllegalStateException: Transaction not active at org.hibernate.ejb.TransactionImpl.rollback(TransactionImpl.java:74) at com.arvato.hibernate.entities.test.HibernateEntityManagerTest.load(HibernateEntityManagerTest.java:77) at com.arvato.hibernate.entities.test.HibernateEntityManagerTest.main(HibernateEntityManagerTest.java:31)
