I also do a lot of batchFetchRelationship and have not seen this.
Yet. We don't often use child EC's so that may explain it.
Strange, hard to reproduce, errors like this can be the result of an
editing context processing notifications sent by another editing
context. Tracking this down can be very difficult. I looked at the
stack trace that Kaj posted but did not see any evidence of this.
It looks like something in EODatabaseContext is hosed.
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.
