This change resulted in the reversal of the order of processInstanceRef and entry in the getProcessInstanceAuditResponse element. This response element is returned by the getProcessInstanceAudit operation in the EventCollectorReportService. To resolve this issue, you must rebuild your application using the newer 4.1 WSDL. Note that the WSDL will not revert to the way it was prior to version 4.1 in future releases.
