Hi, I have question regarding transaction management in ObjectDB. Consider following scenario: Thread 1: try{ EntityManager em = emf.createEntityManager(); em.getTransaction. begin () persist object1 ... { EntityManager em = emf.createEntityManager(); em.getTransaction. begin () persist object2 persist

); //try { tr. begin (); em.persist(r); tr.commit(); //} //catch (...) { } em.close(); emf.close ... .createEntityManager();         em.getTransaction(). begin ();  

.createEntityManager();         em.getTransaction(). begin ();     ... .createEntityManager();         em.getTransaction(). begin ();

Hi, I tried objectdb in following steps: 1, for 1 to 30 {trans. begin (); create typeC o; em.persist(o); trans.commit();} 2, for 1 to 30 {p = em.find(typeC.class, i); print(p)} So simple a test ... . My codes, again, are similar to these: 1. trans = em.getTransaction(); trans. begin (); create typeC o; em
