Create an appropriate error message if Query.setEntity is passed a NULL value ----------------------------------------------------------------------------- Key: HHH-2250 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2250 Project: Hibernate3 Type: Improvement Components: query-hql Versions: 3.2.0.ga, 3.2.1 Reporter: Jonas Maurus Priority: Minor setEntity(xyz, null) ends in a NPE in SessionImpl.guessEntityName(). This previously came up as HHH-675. I just spent hours tracking this NPE in our application, then upgrading Hibernate because I thought it might be a Hibernate bug :-/. The offending line read: .setEntity("customer", user.getCustomer()) "user" being an entity managed by Hibernate with user.customer being a nullable ManyToOne-relation. The current mode of "crash-and-burn" really looks like a Hibernate bug and not like expected behavior. I'd like to recommend that setEntity() should explicitly check for null-values. -- 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
