Thanks Andy. I did see that, and started looking into it, but wasn't sure exactly what to expect. I wasn't 100% sure what
"Image of the Persistable instance when the instance is enlisted in the transaction."
After digging through the tx flow a little bit more, I realized that I needed to set the javax.jdo.option.RestoreValues=true option to force DN to save the image prior to making a field dirty.
Is there anyway to access that savedImage object? I can't find anything in the StateManagerImpl that will give me access to it?
