[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2242?page=all ] Steve Ebersole resolved HHH-2242: --------------------------------- Fix Version: 3.2.2 Resolution: Fixed Assign To: Steve Ebersole In theory, "none" should be fine. Conceptually a joined-subclass would support optimistic-locking="none|version" (please note that version really means version or timestamp). However, the two property-based optimisitc locking schemes (all & dirty) are conceptually not correct with joined-subclasses. We could relax that if we enforced that all properties actually used in optimistic locking occurred in the "base table". But thats not worth the effort. Not sure if you realize, though, but optimisitc-locking="none" is exactly the same thing as optimisitc-locking="version" (or specifying nothing for this attribute) and then *not* defining a <version/> or <timetsamp/>... Anyway, its trivial to change it. So I went ahead and changed the code to explicitly allow optimisitc-locking="none" on joined-subclass. trunk / 3.2 -- 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
