Perhaps, but at my level it seems right (esp. the exception _I_ am getting always contains EOFailedAdaptorOperationKey).
When/if I have more time, I'll try, but at the moment I've got other problems, will write in a moment in another message.

Yup.

Thanks, it did help indeed.

Strangely enough it did work (i.e., it has been removed -- self evidently, internally insertedObjects is a mutable array), but did not help -- this way led to the dreaded "rowDiffsForAttributes: snapshot in com.webobjects.eoaccess.EODatabaseOperation {_dbSnapshot = {}; ..." exceptions.
