[flexcoders] Dynamically Changing Easing Function Again

[Amy]

I am trying to create an easing function explorer to be able to compare 
the existing easing functions.  However, I am having a problem with the 
syntax to change out the function at runtime.  I feel like I am really 
close here, but I am at a loss as to what else to try.  Here is the 
function I am using.

private function onListChange(e:Event):void {
        easingFunction = e.target.selectedItem.label;
        goToBottom.easingFunction = getDefinitionByName
("mx.effects.easing."+easingFunction).easeIn;
        goToTop.easingFunction = getDefinitionByName
("mx.effects.easing."+easingFunction).easeIn;
}
