Trouble with Interactive Debugging of Orchestration Instance
|

| Ron Simmons 2004-04-07, 2:54 pm |
| I am receiving the following exception from somewhere within an atomic scope in my Orchestration:
System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.XLANGs.Core.XSDPart.GetDistinguishedField(String dottedPath)
at ACHCaptureBtk.ACHCaptureStep2.segment4(StopConditions stopOn)
at Microsoft.XLANGs.Core.SegmentScheduler.RunASegment(Segment s, StopConditions stopCond, Exception& exp)
System.NullReferenceException
Scoped@
ACHCaptureStep2.UpdateAutoPymtSrv_AcctRecap
ACHCaptureStep2.MainScope
ACHCaptureStep2.ACHCaptureStep2
I am trying to use the interactive debugger to see what is happening. I've not been able to find more than a single page of documentation about interactive debugging and so I am struggling trying to determine which object has not been instantiated.
I am unable to set a breakpoint anywhere within my atomic scope and do not know how to proceed.
Any advice is greatly appreciated.
Ron

| My first guess would be that you marked something as a distinguished field
and it either does not exists in the document, or has no value. either that
or something has changed about your distinguished field in the schema.

| Thanks Matt,
You were right. My problem appears to be that I've got marked as distinguished properties some node that are defined with minOccurs=0, and when these nodes, or any combination thereof are missing, my orchestration blows.
Does anybody know how to handle that?
