PersistenceUnitUtil.getIdentifier() returning zero instead of null ------------------------------------------------------------------ Key: HHH-5861 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5861 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.6.0 Reporter: Archie Cobbs Priority: Minor In one project my identifiers are Java {{long}} values and my code invoked {{PersistenceUnitUtil.getIdentifier()}} on an entity object which was either newly created and not yet persisted, or newly created and persisted but not yet actually saved (I'm not sure which case it was). But either way, the method returned the wrong thing, namely zero instead of {{null}}. According to the Persistence API, it should have returned {{null}} instead of zero: {quote} _Return the id of the entity. A generated id is not guaranteed to be available until after the database insert has occurred. Returns null if the entity does not yet have an id._ {quote} -- 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
