Bugs with @OrderBy on embedded object

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

Hi,
what do you mean exactly with "embedded", are both publishInfo and position embedded in Category?
I'm no guru here, but they (the gurus) will be more likely to help you if you post the full source code if the entity. If it's complicated maybe you could reduce it to the minimal failing code and then show just that. You should also post the hibernate versions(s) you are using.

regards,
