[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-2980) Error "org.hibernate.HibernateException: cannot simultaneously fetch multiple bags" not specific enough

[Steve Ebersole (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2980?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steve Ebersole updated HHH-2980:
--------------------------------

         Assignee: Steve Ebersole
    Fix Version/s: 3.5
                   3.3.x
                   3.2.x
      Component/s: core

I can offer adding a new exception type which captures the bag 'collection roles' (collection roles are the names of the collections in the form OwnerEntityName.collectionPropertyName).  The message will remain the same, but the new type will expose a "Set/*<String>*/ getBagRoles()" method

> When I get this exception:
> org.hibernate.HibernateException: cannot simultaneously fetch multiple bags
> I don't know what to do except google.  Why not spruce it up a little to say something like:
> For class X, multiple collection fields are marked for eager fetching: a, b, c; this is not supported by Hibernate in releases after 3.2.x
