Steve,
It sounds like in the process of commenting the persistence.xml file,
something in our model must have gotten out of sync, and as a result this
causes the resulting errors you are seeing.
If you exit the Workbench and restart, does this resolve the problems you
are seeing? Can you post your persistence.xml (without sensitive info of
course) if this does not resolve the problem?
Also, can you post the NullPointerException you are encountering? It
seems that the persistence.xml is at the root of this issue. If only 1
persistence unit is active, then the tools should work correctly, so I
would like to see what might be different about your case.
