[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3943) Criteria fails to search ManyToMany associations while setCacheable is true

[TK Kocheran (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33327#action_33327 ] 

TK Kocheran commented on HHH-3943:
----------------------------------

The following line above:
Criteria criteria = session.createCriteria(SupportGroup.class) 

Should read:
Criteria criteria = session.createCriteria(Group.class) 

> Criteria fails to search ManyToMany associations while setCacheable is true

> 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)
