[flexcoders] Custom Event Variables

[trk247]

Using Flex 2.0 - I have a child MXML document that has a custom 
event like this:

child.MXML
<mx:Metadata>
   [Event("selectionChanged")]
</mx:Metadata>

function someFunction() {
  dispatchEvent(new Event("selectionChanged", {x:something.x, 
y:something.y});
}

Now I'm trying to get the values of x and y back into the  
main.MXML file. 

I did create a selectionChanged class and Overrided the inherited 
clone() method like explained here: 
http://livedocs.macromedia.com/flex/2/docs/00001644.html. 

This would have been the old way:
<something selectionChanged="getRestaurantListByArea(event.x, 
event.y);"/> but in Flex 2.0, it gives an error.

Any help appreciated.
