[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2350) 2nd level cache broken for non-inverse bidirectional one-to-many relation

[Gail Badner (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2350?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gail Badner resolved HHH-2350.
------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.6.x)
                   3.6.0.Beta2

Fixed in Branch_3_5 and trunk.

This was fixed by changing ManyToOneType.isAlwaysDirtyChecked() to return true.

If an entity has only its "inverse" many-to-one association that is dirty, its version will be incremented. This was not being done before this fix.

> When using "non-inverse" one-to-many relations as described in  "2.4.6.2.3. Bidirectional association with indexed collections" (http://www.hibernate.org/hib_docs/annotations/reference/en/html/entity.html#entity-hibspec-collection-extratype) hibernate is wrong when activating 2nd level cache.
> See the attached example (unzip in /usr/local/hibernate-annotations-3.2.1.GA, testname=org.hibernate.test.annotations.invonetomany.InverseOneToManyTest).
> More details can be found here: http://forum.hibernate.org/viewtopic.php?t=969456 (and also in InverseOneToManyTest.java).
