Problem with CasCadeType.ALL during persist when processing OneToMany hierarchy relationship -------------------------------------------------------------------------------------------- Key: EJB-348 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-348 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.2.GA Environment: 3.2.2.GA , Microsoft SQL Server 2000 SP4, JTDS 1.2.2 Drive Reporter: George Daswani Attachments: TestProject.zip [Computer] private Set<NetworkInterface> networkInterfaces ; @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "computer") @JoinColumn(name = "COMPUTER_ID") public Set<NetworkInterface> getNetworkInterfaces() --------------------- [Network Interface] private Computer computer; private Set<IPAddress> ipAddresses; @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "CMP_ID", nullable = false) public Computer getComputer() @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "networkInterface") @JoinColumn(name = "IP_ID") public Set<IPAddress> getIPAddresses() --------------------- [IPAddress] private NetworkInterface networkInterface; @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "NI_ID", nullable = false) public NetworkInterface getNetworkInterface() --------------------------------------------------------------------------------------------------- Note: works just fine with TopLink Essentials. When two or more IP addresses are added to a network interface, Hibernate JPA errors out when persisting the "Computer". Example: Computer computer = new Computer(); // ASSIGNED ID computer.setId("COMPUTER1"); computer.setAssetTag("AC1"); NetworkInterface networkInterface = new NetworkInterface(); networkInterface.setMacAddress("00:00:00:00:00:00"); computer.addNetworkInterface(networkInterface); IPAddress ipAddress1 = new IPAddress(); ipAddress1.setIpAddress("192.168.1.1"); networkInterface.addIpAddress(ipAddress1); IPAddress ipAddress2 = new IPAddress(); ipAddress2.setIpAddress("192.168.1.2"); networkInterface.addIpAddress(ipAddress2); entityManager.persist(computer); ---------------- ERROR ----------- - INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK92788228A23'. The conflict occurred in database 'TestDB', table 'NI', column 'NI_ID'. - Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update Caused by: java.sql.BatchUpdateException: INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK92788228A23'. The conflict occurred in database 'TestDB', table 'NI', column 'NI_ID'. seems like some sort of wrong INSERTION order.
