I then read about the insertObject: in<Key>AtIndex: method.
Reading the documentation it seems this should be called by the
NSArrayController if its implemented by its content array (in my
case AppController).

The description of this bug suggests it's specific to Core Data and
the contentSet binding. I got the impression from Mr. Hall that he's
not using Core Data here, nor the contentSet binding. Does this still
apply?
Phillip, did you _only_ implement an insertObject:inVegetablesAtIndex:
method, or did you implement the full complement of indexed to-many
accessors? See the comment at the declaration of the -
mutableArrayValueForKey: method in NSKeyValueCoding.h to see which
methods you would have to implement before the indexed to-many
accessors would be used. (I'd direct you to the documentation for -
mutableArrayValueForKey:, but it isn't as complete as the comment in
the header.)
In short, you would need:
-countOfVegetables
At least one of: -objectInVegetablesAtIndex: or -vegetablesAtIndexes:
At least one of: -insertObject:inVegetablesAtIndex: or -
insertVegetables:atIndexes:
At least one of: -removeObjectFromVegetablesAtIndex: or -
removeVegetablesAtIndexes:
Cheers,
Ken
