Rob, I'm having a bit of trouble understanding exactly what you are trying to do. Could you post some of your code so that we get a better idea of what is going on, please? Yours, Mike.

I came across a problem when returning SDOs from services exposed with the JSONRPC binding ( http://issues.apache.org/jira/browse/TUSCANY-1337) that is not fixed yet. In my case it was to do with returning types represented by generated SDO classes. The JSONRPC binding was struggling trying to serialize the underlying EMF classes. I wasn't getting a NPE though. As Mike says if you could provide a bit more detail of your scenario we can work out if this is the same problem or a new one. As a work round I created a class to represent the complex type manually and returned that. Regards Simon
