Hi again,
I still can't figure out why the qualifier (below) is causing a
java.lang.NullPointerException. If I specify null for the qualifier
in the FetchSpecification - it works without a problem - but
utilising the ( EOQualifier )recentPurchasesQualifier below causes a
RuntimeException.
Any help?
the toString output of my qualifier is as follows:
((timestamp > (com.webobjects.foundation.NSTimestamp)'2005-07-06
00:00:15 Etc/GMT') and (accountsInvoiceNumber = null) and
(deliveryConsignmentNumber = null))
Thanks.

(Below is the FetchSpecification used and the runtime exception,
though there's nothing special in Main that's worth seeing seeing
as it's the qualifier causing the problems).
