[Christian Bauer (JIRA)]

Christian Bauer resolved EJB-304.
---------------------------------

    Resolution: Rejected

So submit your implementation of multiple bag fetching to existing JIRA issues and don't open new ones. Hibernate passes the Sun TCK for JPA.

>                 Key: EJB-304
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-304
>             Project: Hibernate Entity Manager
>          Issue Type: Bug
>    Affects Versions: 3.2.0.cr1
>         Environment: JBoss4.0.4.GA
>            Reporter: Morten Andersen-Gott
>
> Having more than one relationship on en entity annotated with @OneToMany(fetch=FetchType.EAGER) causes exception when deploying the ejb3 module:
> org.hibernate.HibernateException: cannot simultaneously fetch multiple bags.
> This bug is thoroughly explained here:
> http://www.jroller.com/page/eyallupu?entry=hibernate_exception_simultaneously_fetch_multiple
> and depends on HHH-1718 "Have multiple bag fetches revert to subselect fetching for all but one of the bags"
> The temporary solution in HHH-1413 - disallowing multiple bag fetches is unsuitable to ejb3 environment, because the spec does not disallow it.
