Symptoms

Getting an “object reference” error gets thrown when trying to execute a READ method against one of the SmartObjects exposed by the following webservice - http://spectrum.rovantexas.com:8082/ws/PurchaseOrder?wsdl

See video demo: http://screencast.com/t/m5hCc90Lpk


However, running any of the other web service return successful results. In addition, if you run this web service from the SoapUI, it get's back the expected results.
No entries trace is captured in Fiddler – this will suggest the error is occurring even before we hit the web service.

 

Diagnoses

The web service endpoint in this particular scenario had a different behavior in that where we normally have an empty instantiated header it had a NULL, so needed to add a null check in the code.
 

Resolution

This is now resolved. The FIX itself is part of Appit 1.4 Update 2 release that rolled out on July 7.
