And, it's the Labor Day Holiday in the United States today and all of
Autodesk has been off for the last week as part of their cost-saving

And some of us go on vacation once in a while...

In any case, it sounds like you should be listening for
Fusion.Event.MAP_LOADED event which gets fired when the Map object is
loaded and ready.  FUSION_INITIALIZED is fired when the AppDEf has been
parsed and widget objects created.
