Flex Type Coercion, it was smart, I think

Question

I have a class essentially:

public class WindowEvent extends Event
{
    public static const WARNEVENT:String = "warnEvent";
    public static const TASKREQEVENT:String = "taskRequestEvent";
    public static const TASKANNOUNCE:String = "taskAnnounce";
    public static const WINDOWCHANGE:String = "windowChange";
    public static const ILLEGALPOSITION:String = "illegalPosition";

    // insert brevity   
}

The first four events worked fine, but I just added ILLEGALPOSITIONand tried this:

    // inside Window.as
    private function checkDimensions():void {
       if(!Window._legalBoundaryEnable)
           return;
...    var pass:Boolean = Window.legalBoundary.containsRect(
455        this.getBounds(stage));
456    if(!pass) {
457        this.dispatchEvent(new WindowEvent(WindowEvent.ILLEGALPOSITION,
...           "Illegal Position etc."));
       }
    }

So Flex hit this stack with me when I hit the send method:

TypeError: Error # 1034: Type Coercion failed: cannot convert ¬

, Window.as:457 - . , WTF flash.events.EventDispatcher.dispatchEventFunction MouseEvent?

Answer 1
