insertObject() is only for newly created objects, not fetched objects.  
Fetching places the object into the EOEditingContext.

that only works if ctx is the same object instance in both cases.  Try the 
seemingly redundant:

EOGenericRecord eo = (EOGenericRecord) value;
EOGlobalID globalID = eo.editingContext().globalIDForObject(eo);

If you get an NPE, then eo is not in an editing context.
