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.

[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

> 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.

[Hibernate-JIRA] Created: (HV-491) Add support for MOD11 Algorithm
by George Gastaldi (JIRA)
Add support for MOD11 Algorithm
-------------------------------
Key: HV-491
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-491
Project: Hibernate Validator
Issue Type: Improvement
Components: validators
Reporter: George Gastaldi
It would be nice to add support for the MOD11 algorithm. It is described on http://joselop.es/mod-11 or http://en.wikipedia.org/wiki/MSI_Barcode#Mod_11_Check_Digit and it is widely used on Brazil, such as CPF (Cadastro de Pessoa Física - http://en.wikipedia.org/wiki/Cadastro_de_Pessoas_F%C3%ADsicas), CNPJ (Cadastro de Pessoa Jurídica - National Registry of Corporations) and Título de Eleitor (Voter ID card)
