You can create a custom accessor and re-create the cache if it is not
present when the accessor is called.

I have custom data caches associated with a managed object.
The documentation states didTurnIntoFault "method may be used to
clear out custom data caches". So far so good.
I was creating custom data caches in awakeFromFetch (or
awakeFromInsert) until I realized that awakeFromFetch does not
participate in undo. The documentation confirms that "change
processing is explicitly disabled around this method".
So Apple provides a way to remove custom data caches associated with
a managed object but no way to create them.
Any thoughts on this?
