creationComplete="navigatorcontent1_creationCompleteHandler(event)">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
import mx.events.ValidationResultEvent;

protected function navigatorcontent1_creationCompleteHandler(event:FlexEvent):void

{ dispatchEvent(new ValidationResultEvent(ValidationResultEvent.INVALID)); }

]]

Expected Results: No error

Workaround (if any): The error happens in
override public function dispatchEvent(event:Event):Boolean

{ if (dispatchEventHook != null) dispatchEventHook(event, this); return super.dispatchEvent(event); }

From UIComponent, in super.dispatchEvent(event). Once It´s not possible see the method in superclass, I could not make a deep investigation. It seems the method want a FlexEvent instead of an Event, the super class of ValidationResultEvent. Maybe just changing the superclass could sover the issue.
