[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-5531) Version update on read-only entity fails for joined subclasses

Version update on read-only entity fails for joined subclasses -------------------------------------------------------------- Key: HHH-5531 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5531 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.5, 3.6.0.Beta4 Environment: MySql 5.1.37-1 (ubuntu) Reporter: Tobias Bergman Assignee: Gail Badner Fix For: 3.6.5, 4.0.0.Beta1 Attachments: hibernate-inheritance-bug.zip When adding an item to a collection for which the owner is fetched as READ_ONLY the version update fails if the owner class has a parent class (with a join strategy), but without parent it works. The problem is that the AbstractEntityPersister.getTableUpdateNeeded() returns with getTableHasColumns() (line 2748) when the owner is fetch as READ_ONLY. For a single table this probably works by luck. But what is the correct behavior? Should it be possible to update an READ_ONLY fetched owner's collection?
