KVO: subclasses registering keys fror same dependent key

Subject: KVO: subclasses registering keys fror same dependent key

Apparently (but not really surprisingly)

+ (void)setKeys:(NSArray *)keys triggerChangeNotificationsForDependentKey:(NSString *)dependentKey

does the wrong thing if a class and it's subclass use it on the same dependent key. Instead of merging the lists, the keys set by the subclass win and the ones set in the superclass are lost.

Is there any way to access the keys defined in the superclass and ADD to them rather than REPLACE them?

Gerd
