Hi!

Just fyi I now get the

[2004-01-13 13:51:24 MET] <WorkerThread6> java.lang.NullPointerException
         at 
com.webobjects.eocontrol._EOMutableKnownKeyDictionary.<init>(_EOMutableKnownKeyDictionary.java:90)
         at 
com.webobjects.eoaccess.EORelationship._foreignKeyForSourceRow(EORelationship.java:1094)


stacktrace when I don't use batchFetchRelationship.

We use prefetching in the fetch where I get this exception.

The ec here is session.defaultEditingContext.
