[Hibernate-JIRA] Created: (HHH-5368) Not throwing Optimistic Lock when the entity is attached

by Fernando Rubbo (JIRA)

Not throwing Optimistic Lock when the entity is attached -------------------------------------------------------- Key: HHH-5368 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5368 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1 Environment: windows XP, jboss 4.3 EAP, hibernate 3.4.2.sp1 Reporter: Fernando Rubbo Priority: Minor Hi Hibernate is not throwing Optimistic Lock when the entity is attached. It happens when the business rule sets a version in the attached entity that is less than its original (from database) version value. Take the following code as an example of the bug. // inserts A A a1 = new A(); a1.setName("A1"); dao.persist(a1); dao.flush(); dao.clear(); // as expected, the piece of code below works just fine final A a2 = dao.find(A.class, new BigDecimal(1)); a2.setName("A2"); dao.merge(a2); dao.flush(); dao.clear(); // as expected, this code fails due to Optimistic Lock try{ final A a3 = dao.find(A.class, new BigDecimal(1)); dao.clear(); a3.setName("A3"); a3.setVersion(0); //database verison is 1 dao.merge(a3); dao.flush(); Assert.fail(); }catch (Exception e) { System.out.println(e.getMessage()); // ignore }finally{ dao.clear(); } // unexpectedly, the piece of code below also works.. // even with the version being less than the one in the database // Note that this happens because hibernate is holding internaly the original version of the entity. // Even when the version is manually changed it keeps using the original one. final A a3 = dao.find(A.class, new BigDecimal(1)); a3.setName("A3"); a3.setVersion(0); //database verison is 1 dao.merge(a3); dao.flush(); dao.clear(); This problem can be handled by the business rule. For example, whether the version that comes from the screen is smaller than the one from the database it could throw an Optimistic Lock exception. However, it it was not handled, hibernate must take care of this in the same way it does with detached objects. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Commented: (HHH-1152) Value object(<component>) inheritance mapping

by Mircea D. (JIRA)

[ https://hibernate.onjira.com/browse/HHH-1152?page=com.atlassian.jira.plug... ] Mircea D. commented on HHH-1152: -------------------------------- I think this also affects every release after 3.1 beta 2 including 5.0. > Value object(<component>) inheritance mapping > --------------------------------------------- > > Key: HHH-1152 > URL: https://hibernate.onjira.com/browse/HHH-1152 > Project: Hibernate ORM > Issue Type: New Feature > Components: core > Affects Versions: 3.1 beta 2 > Reporter: Vjeran Marcinko > Priority: Minor > > Though fine-grained object mapping is one of Hibernate's main objectives, it still doesn't support *value object* (<component>) inheritance mapping, only entity inheritance mapping. > It would be best if <component> tag could also contain similar tags for inheritance as entity does. -- This message is automatically generated by JIRA.
