Deleting ManagedObject with no undo... (fails testing)

Hi,

I'm in the testing phase of my framework, and one of my methods used 
to delete an NSMangedObject without undo (used for certain 
circumstances) fails its test when it asks the deleted object if its 
deleted via isDeleted.....

My method is as folows:

- (void)deleteSelfWithoutUndoRegistration
{
   NSManagedObjectContext *theContext = [self managedObjectContext];
   NSUndoManager *theUndoManager = [theContext undoManager];
   
   [theContext processPendingChanges];
   [theUndoManager disableUndoRegistration];
   [theContext deleteObject:self];
   [theContext processPendingChanges];
   [theUndoManager enableUndoRegistration];
}

And the test for it is:

- (void)
test__NSManagedObjectAdditionsTests___deleteSelfWithoutUndoRegistration
{
   NSUndoManager *contextUndoManager = [testContext undoManager];
   STAssertNotNil(contextUndoManager,nil);
   
   NSManagedObject *aManagedObject = (NSManagedObject *)
[NSEntityDescription insertNewObjectForEntityForName:@"Test_Entity" 
inManagedObjectContext: testContext];
   STAssertNotNil(aManagedObject,nil);

   unsigned undoLevelsBefore = [contextUndoManager levelsOfUndo];
   [aManagedObject deleteSelfWithoutUndoRegistration];
   unsigned undoLevelsAfter = [contextUndoManager levelsOfUndo];
   
   STAssertTrue([aManagedObject isDeleted],nil);     //TEST FAILS HERE
   STAssertEquals(undoLevelsBefore,undoLevelsAfter,nil);
}

The testing NSManagedObjectContext is set up to be an in-memory store 
with a nil URL/Options/etc. Is there anything I can do about this?
Commenting out the undo registration methods cause isDeleted to 
return YES, therefore turning off undo registration causes it to 
return NO... whats up with that?

Any clue?
