Hi Erich, I'm looking at this but currently I am getting an exception generated here ...
saveGraph(staticGraph); I'll investigate why this might be. Have you seen anything like this? I noticed I had to do some changes to your code to make it compile, which implies you are using some generator options. For completeness, can you let me know what generator options you are using.

The dynamic approach using the commonj.sdo.DataGraph works fine.
