I'm calling 5 identical web service calls using a parallel for loop in BPM. Obviously the data in each slightly differs. Why would this call suspend the process and give the following errors:
handleCommunicationError( ErrorContextData, Throwable, TransitionTicket ): A technical error occurred.
Interface namespace = myNamespace
Interface name = myService
Operation name = myOperation
Connectivity type = WS
Application name = myAppName
Reference name = 8bd95deb-8cf1-453d-94e5-0576bb385149
Message Id = null
WS style = DOC
Start time of WS call = 2014-02-26 17:51:23.297
Return time of WS call = 2014-02-26 17:51:23.412
Principal name = SAP_BPM_Service
Root error message = local part cannot be "null" when creating a QName
Error message = Could not invoke service reference name 8bd95deb-8cf1-453d-94e5-0576bb385149, component name myComp application name myappname
com.sap.engine.interfaces.sca.exception.SCADASException: Could not invoke service reference name 8bd95deb-8cf1-453d-94e5-0576bb385149, component name

Surely if it was the service group unassign then reassign issue then none of the calls would have worked?
