PRB: Do not forget to specify event handlers if you call addEventHandler!

I examined the code closer and found out that it looks as follows:

if (iu.getControlType() == "ActiveX"){

        //... skipped for brevity

	function ImageUploader1_BeforeUpload() {
            //... skipped for brevity
	}


	function ImageUploader1_Progress(Status, Progress, ValueMax, Value, StatusText) {
            //... skipped for brevity
	}
}

iu.addEventListener("BeforeUpload", "ImageUploader1_BeforeUpload");
iu.addEventListener("Progress", "ImageUploader1_Progress");

As you see if you run this code under Firefox, getControlType will return "Java" and no event listeners will be defined.

I got a suspicion that if you run such code, Live Connect (mechanism which is used in Java applets to access DOM and JavaScript) will crash with some exception, and probably it will not work anymore. In particular it would mean that Image Uploader will not be able to redirect. Also, I guess no event handlers and maybe even no JavaScript methods will work.

I checked this suggestion on clean Basic Demo - just called addEventListener with invalid function name. And it proved my suspicion.

I hope guys will fix it in nearest updates. Meanwhile everyone who experience strange issues with RedirectUrl property or some JavaScript operations with Image Uploader in Java version, I suggest to make sure that all event listeners are specified properly.
