There is a problem with updateInstance(). You throw the previous Singleton._instance away. Put this in front of Main() function to see that you lose old values:

Singleton.getInstance().initializeMyValue();
trace(“after = “, Singleton.getInstance().myValueNotInitialized);
trace(“after (1) = “, SingletonExtended.getInstance().myValueNotInitialized + ” >>> from SingletonExtended”);
trace(“after (2) = “, Singleton.getInstance().myValueNotInitialized + ” >>> from Singleton”);

This is sweet. A game we were working on required this type of pattern and this worked perfectly.
