NSArray not re-sorting when the value of its sort descriptor key changes

Hi everybody,

Just got a question. I have an NSArrayController that holds NSManaged objects.
The managed objects have a key (number) that returns a number, and the NSSortDescriptor
also sorts by "number," so whenever I insert an object, the list rearranges itself to the sort description
yet if I edit the value at key "number" NSArrayController doesn't realize the value changed and fails to
re-arrange the array... without subclassing NSArrayController is there anyway to auto-sort when the key
changes without too much trouble?
