[CDO] org.eclipse.emf.cdo.common.util.PartialCollectionLoadingNotSupportedException [message #989236]

[Using hibernate store] I am getting the following exception when comparing two revisions.
Do I miss some settings?

Stack trace:

org.eclipse.emf.cdo.common.util.PartialCollectionLoadingNotSupportedException: List contains proxy elements

In your client, do you enable partial collection loading explicitely? If yes, the HibernateStore might not support it.
If no it might be a bug in the HibernateStore that makes it return list element proxies which can't resolve later.

May we see the complete stack trace to get a hint on why compare is being called?

No, nothing related to "partial collection loading" when session is set up on client side.

I am calling CDORevision.compare() like described in the HibernateStore docs for auditing:

http://wiki.eclipse.org/CDO/Hibernate_Store/Auditing#CDOUtil.getRevisionByVersion_-_Comparing_revisions

This is due to the following bug as the cdo layer does not return the old value in a CDOSetFeatureDelta:
