Hi,
Its probably a good idea to (re)read the dev guide section about working
with events as it may help clear this up for you. The general problem is
that the VO is not part of the parent child hierarchy of the app so it
cant bubble up the chain.
Your globalVO needs to either (a) dispatch an event on the application
itself(not a good idea) or (b) your application needs to listen to the
globalVO. There are other alternatives aswell but these should be a help
to you right now.
(a) Application.dispatchEvent("globalChange"); //or similar (in VO).
(b) globalVO.addEventListener("globalChange", globalVOChangeHandler);
Option (b) will mean your globalVO will need to be an EventDispatcher
subclass or have an EventDispatcher instance variable and a custom
method for attaching an event listener to the instance variable event
dispatcher(know what i mean?).

FYI. There is a property_change event(or some similar name) that makes
this pretty easy. eg)
class Foo{
var x:Number=0;
funciton Foo(){
addEventListener(PropertyChangeEvent.propertyChange,
handlePropertyChange);
}
function handlePropertyChange(e:PropertyChangeEvent):void{
if (e.property == "x" || e.property == "y"){
//do something.
}
}
}
HTH.
