bizarre event behaviour in flash AS3

Question

This is the strangest most unexplainable and frustratng thing I've experienced with flash and I have no Idea how to solve the problem.

Consider this function

public function trackDownloadHandler(event:MP3DownloadEvent):void
  {
   dispatchEvent(event);
   //dispatchEvent(new MP3DownloadEvent(MP3DownloadEvent.OPEN,event.channelPadID))
  }

I've done this a million times. A particular event arrives in a handler had a dispatch it again from the class it arrived to.

But for some bizarre reason I'm getting an error saying

TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::Event@a06ebe1 to com.rocudo.audioEngine.events.MP3DownloadEvent.

I don't see where I'm trying to convert anything anywhere?

So I tried next to maybe just dispatch a brand new event instead and see how that worked out. The implementation is here below.

public function trackDownloadHandler(event:MP3DownloadEvent):void
  {
   //dispatchEvent(event);
   dispatchEvent(new MP3DownloadEvent(MP3DownloadEvent.OPEN,event.channelPadID))
  }

But in that case the original type error message goes away and I get a new error saying

Type was not found or compile time constant :Vector

What the hell is going on ??

Answer 1

Maybe it's in the event dispatch that calls trackDownloadHandler(event:MP3DownloadEvent)? If you're just dispatching a vanilla Event, then the error you're getting would make sense.

Answer 2

I think the problem may be with not having a clone method defined in your custom MP3DownloadEvent.

Adobe Livedocs flash.events.Event clone()

Returns a new Event object that is a copy of the original instance of the Event object. You do not normally call clone(); the EventDispatcher class calls it automatically when you redispatch an event—that is, when you call dispatchEvent(event) from a handler that is handling event.

For your Vector error, I believe Vectors are only available in CS4. So, if you are using code written for CS4 (and using Vecotrs), and you are compiling with CS3, you would likely get an error like this.
