[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2667) 'illegal attempt to dereference collection' when using auto-join

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2667?page=c... ] Jeff Pae-Corr commented on HHH-2667: ------------------------------------ I provide support for a web-app that uses Hibernate 3.x. At this time I am not able to provide the version number of Hibernate as those were removed from the jar names, but I get the same behavior. Per the opening description I changed this: List assignments = find("from Assignment a where a.assigner.locations.name = ?",schoolName); to List assignments = find("from Assignment a join a.assigner.locations s where s.name = ?",schoolName); to attempt to resolve the issue. The problem is that next I am trying to run deleteAll(assignments) but it fails on a java.lang.ClassCastException: [Ljava.lang.Object; I believe this is probably due to the fact that properties from objects other than Assignment are also being pulled into the List since I am using join. The original query worked fine before the Hibernate update. -- 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
