JPA commit Issue

Question

Hi All ,
I am try to insert a record for my table , i am using
factory = ConnectionHandler.getEntityMgrFactory();
em = factory.createEntityManager();
em.getTransaction().begin();
em.persist(grplevel);
em.getTransaction().commit();
(grplevel is an object) when it runs em.getTransaction().commit() method (last line) it gives this error :
org.apache.openjpa.persistence.InvalidStateException: Detected reentrant flush. Make sure your flush-time instance callback methods or event listeners do not invoke any operations that require the in-progress flush to complete.
can any one help me
Thanks

Hello,
The exception seems to indicate that application event might be being executed that causes a flush, and OpenJPA doesnt allow a flush to occur during a flush.
Since you are using OpenJPA, you might want to post on the Apache forum, but you might also check to see if you have any events registered that would get executed during the commit/flush that could in turn cause a flush to occur - for instance querying with FlushModeType.auto would cause a flush to occur. If that is the case, you might want to switch to using FlushModeType.Manual on the query.
Best regards,
Chris
