Bugs with @OrderBy on embedded fields ?

Hi guys.

Before opening a JIRA I just want to make sure that there's a bug with @OrderBy on embedded fields .

Code:

    @OneToMany(cascade = CascadeType.ALL, mappedBy = "category")    
    @OrderBy("publishInfo.position")
    public Set<Category> getChildren()
    {
        return children;
    }

Where publishInfo is an embedded object inside the Category object.

The stack trace :

Code:

Caused by: java.lang.NullPointerException
   at org.hibernate.cfg.annotations.CollectionBinder.buildOrderByClauseFromHql(CollectionBinder.java:851)
   at org.hibernate.cfg.annotations.CollectionBinder.bindOneToManySecondPass(CollectionBinder.java:608)
   at org.hibernate.cfg.annotations.CollectionBinder.bindStarToManySecondPass(CollectionBinder.java:563)
   at org.hibernate.cfg.annotations.CollectionBinder$1.secondPass(CollectionBinder.java:517)
   at org.hibernate.cfg.CollectionSecondPass.doSecondPass(CollectionSecondPass.java:43)
   at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1130)
   at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:316)
   at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1115)

Does anyone meet already this problem ?

Cheers

I have the same problem.

There is a JIRA about that :
http://opensource.atlassian.com/projects/hibernate/browse/ANN-617

**************
It seems to be in Hibernate Annotation : Exception is happening in "org.hibernate.cfg.annotations.CollectionBinder....."

in JBoss, I have seen that the hibernate-annotations.jar is also in the .../jboss-4.2.2.GA/client folder.

In my config, I did not updated this lib....
I wonder if it may be the reason of this exception, related to the JIRA...

will do a check....

*************
Anyway, if any one have an idea about that @orderBy problem ?....

Well...
I have not change anything in the ".../jboss-4.2.2.GA/client" folder (which should not be involved in anything with this problem).

but I updated the hibernate-annotations package with the last recent one : hibernate-annotations-3.3.1.ga.jar

(and hibernate-entitymanager-3.3.2.ga.jar).

The exception is not throwing anymore...
