That's fairly strange, it looks like a DOM level error where the node
structure is not correct. It's raised in the following assignment (when ODE
reads the content of the incoming message variable):
<copy>
<from>$ReadGraphOut.payload/ns3:graphRdOut</from>
<to>$AnalyzeGraphIn.payload/ns5:graphIn</to>
</copy>
Also is your process persistent or in memory?
Thanks,
Matthieu
