NullPointerException in XMLSaveImpl$Lookup
I am trying to save an SDO which I created using the EMF APIs. I am
using the following code found in the 'Introduction to SDO' example to
print out the result as XML:
EDataGraph dg = SDOFactory.eINSTANCE.createEDataGraph();
dg.setERootObject(eObject);
dg.getDataGraphResource().save(System.out, null);
I get an NPE down in
XMLSaveImpl$Lookup.featureKind(EStructuralFeature).

I am looking for the EMF source code for the version we are working with
currently so I can see what's going on, but I think this might be caused
by something I am not doing while creating the EClass info for the
object being serialized. ??

Brian,
This looks like SDO 1 (EMF) code, that is, nothing to do with the Tuscany
SDO (2) project here.
I'd suggest posting your question to the EMF newsgroup at Eclipse.
Frank.
