Hi all, I'm new in JPA / JDO and I'm totally sure I'm doing something wrong. I don't know why I can't see children objects in the same transactions using the same PM
____________________________________________________________________ // Here I got the DatastoreEntityManager (id=92) DAO dao = DAO.getInstance(DAO.JPA, requestor); // Here I got the DatastoreEntityTransactionImpl (id=94) dao.startTransaction() // Then I create and maker persistent a new Department (id=114) // It uses the same DatastoreEntityManager (id=92) and DatastoreEntityTransactionImpl (id=94) Department department = new Department() department.setName("New department"); dao.persist(department); dao.refresh(department); // Then I create and make persistent a new Account (id=224) Account account = new Account(); account.setNumber(12345); account.setDepartment(department); // Owned relationship working fine dao.persist(account); dao.refresh(account); // Now I'm testing it department.getId() // returns Department(22) account.getId() // returns Department(22)/Account(24) department.getAccounts(); // Returns an empty list __________________________________________________________ At some point down the line I gotta get the accounts in the same transaction to use in another entity. I've tried to add manually the new Account to the* Department.accounts* field but when I tried to do it I get *javax.jdo.JDODetachedFieldAccessException:* You have just attempted to access property "accounts" yet this property was not detached when you detached the object. Either dont access this property, or detach it when detaching the object. Does someone faced the same?? I'm loosing my hair with this!!
