Criteria fails to search ManyToMany associations while setCacheable is true --------------------------------------------------------------------------- Key: HHH-3943 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3943 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.1 Environment: MySQL 5, Hibernate 3.3.1 Reporter: TK Kocheran When using the Criteria API to search for values in ManyToMany associations, if setCacheable is true, Hibernate will fail to find certain objects. I have confirmed this problem both when using unidirectional and bidirectional ManyToMany associations. The scenario kind of looks like this: @Entity @Table(name='group') public class Group { ... @ManyToMany(targetEntity=User.class) @JoinTable(name="group_members") private List<User> members; ... } When searching for specific groups, I will often form criteria like this: Criteria criteria = session.createCriteria(SupportGroup.class) .setTimeout(10) .setCacheable(true) .createAlias("members", "members") .add(Restrictions.eq("members.username", "tomSawyer")); Executing this criteria will fail to retrieve any results. Only when setCacheable is set to false will results be returned. (I have confirmed through other means that I can get access to the entities matching these restrictions) -- 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
