[mapguide-users] Error with MGOS 2.0 and Fusion

[Mike Adair]

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.
