Discriminator column in the joined table ----------------------------------------- Key: HHH-4466 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4466 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Xavier Jodoin Attachments: UsertypeExample.zip When using the JOINED inheritance strategy and creating a link to the root Entity of the hierarchy, hibernate only puts the id in reference and thus when the entity is loaded lazily, hibernate joins all subclasses because it can't know which Entity is being referred to. It would be useful to support having a discriminator column in the joined table to specify the instance class. It is possible to emulate this feature with an usertype but some features like querying become harder to implement. -- 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
