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, StopConditi
ons 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 interac
tive debugging and so I am struggling trying to determine which object has n
ot been instantiated.

I am unable to set a breakpoint anywhere within my atomic scope and do not k
now 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 distinguis
hed properties some node that are defined with minOccurs=0, and when these n
odes, or any combination thereof are missing, my orchestration blows.

Does anybody know how to handle that?

Ron
