Hy,

I keep getting this exception:

java.lang.NullPointerException
        at org.apache.cayenne.access.DataRowStore.sendUpdateNotification(DataRowStore.java:673)
        at org.apache.cayenne.access.DataRowStore.processSnapshotChanges(DataRowStore.java:538)

...

on Cayenne 2.0.2.

This seems to happen always for the same Local EJB, while other Local
EJBs that use Cayenne in the same way seem to work. From a previous
email, it seems this has something to do with the serialization of the
objectStore.

What can I do to get rid of this ?

Thanks,
