Multi-threaded Delete Failures Not Logged

Problem: If you have multiple requests from different devices trying to delete the same record at the same time, and a thread successfully deletes the record, but a second thread fails because that record is now removed from the server, no failure message appears in the Unwired Server log.

Solution: Use the old value argument in Unwired WorkSpace for optimistic concurrency control (OCC). See Sybase Unwired WorkSpace - Mobile Business Object Development > Develop > Working with Mobile Business Objects > Mobile Business Object Data Properties > Old Value Argument.
