[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4744) Incorrect audit entity for TABLE_PER_CLASS with abstract classes (results in query error)

[Daniel Bleisteiner (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=36167#action_36167 ] 

Daniel Bleisteiner commented on HHH-4744:
-----------------------------------------

In my case I have two abstract classes in the hierarchie and it helped to define the inheritance stategy at all abstract levels: @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) - this avoids the creation of the unneccessary version tables.

>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: envers
>    Affects Versions: 3.2.0.ga, 3.5.0-Beta-2

> The configuration code of Envers does not check the abstract flag of a PersistentClass. Thus the created audit entity is not declared as being abstract. Abstract entities do not have concrete tables. Without declaring the audit entity of a super class as being abstract, queries include a table (that does not exist) for the abstract super class. 
> I have added a patch for the trunk and for Envers 1.2.2.
