Try refreshing the proxy. When you see a null response coming back, it
often means that the serializer did not see the right content that it
expected on the wire.

Further to my earlier email....
The response (results()) is null when the method call returns from the
webservice as per the following code in the proxy class:
Dim results() As Object = Me.Invoke("process3ParmRequest", New
Object() {inputHeader, messageControlPayload, inputMessage})
The results of the immediate window are:
?results(0)
Nothing
