you can do the following

Flex2B2
Parent

DesignView[0].addEventListener("selectionChanged", valueChanged)

function valueChanged(event:SelectionChangedEvent):void
{
currentSelection = event.selection;
adjustControls(event.style);
}

create a class called SelectionChangedEvent as follows

package
{
import flash.events.Event;

public class SelectionChangedEvent extends flash.events.Event
{
    public var selection:String;
    public var style:Object(not sure what type style settings is)
   
    public function SelectionChangedEvent(_selection:String,
_style:String);
    {
       super("selectionChanged");
       selection = _selection;
       style = _style;
    }
}
}

>       [Event("showBorders")]
>       [Event("selectionChanged")]
> </mx:Metadata>
>
> dispatchEvent({type: 'selectionChanged', selection:
> event.target.getChildAt(0).id, style: styleSettings});
>

Child
<mx:Metadata> is the same

dispatchEvent(new Event(event.target.getChildAt(0).id,
styleSettings));


my suggestion is based on the flex2 samples example
