Comment

See Tracking object creation and removal before continuing.

This time the recorded object is given a non-temporary EOGlobalID (Output C) and therefore it appears in the list of deletedObjects at the end (Output G)

Output

A) 0 insertedObjects, 0 registeredObjects, 0 deletedObjects
B) 0 insertedObjects, 1 registeredObjects, 0 deletedObjects
C) GlobalIDForObject VfL Bochum 1848 = <PermanentGlobalID 0x1085e0 (hash=0x42F153F4)>
D) 1 insertedObjects, 2 registeredObjects, 0 deletedObjects
E) GlobalIDForObject Mulle kybernetiK = <EOTemporaryGlobalID 0x114550 (hash=0x85281286)>
F) 0 insertedObjects, 1 registeredObjects, 0 deletedObjects
G) 0 insertedObjects, 1 registeredObjects, 1 deletedObjects
