externally loaded image disappears??
In my swf, the user can upload and image and edit it. The can move and scale the image.
When I test this in flash, it works great. But, when I try it out on the testing server, it works ok for about 8 seconds and then if you try to do anything to the image after that, the image disappears which is not good.
Below is all the script that drives this. Not sure what the problem is.
var isMetal:String = loaderInfo.parameters.isMetal;
//Handles Image Logo Upload
//filter image types that can be uploaded
var logoLoaded: Boolean;
var file:FileReference = new FileReference();
var imageTypes:FileFilter = new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg; *.jpeg; *.gif; *.png");
var allTypes : Array = new Array(imageTypes);
file.addEventListener(Event.SELECT, fileSelect);
file.addEventListener(Event.COMPLETE, fileComplete);
UploadBTN.addEventListener(MouseEvent.CLICK, UploadImage);
UploadBTN.buttonMode = true;
UploadBTN.useHandCursor = true;
UploadBTN.mouseChildren = true;

file.addEventListener(ProgressEvent.PROGRESS, progressHandler);
file.load();
}

{
trace("File load error");
}
function progressHandler (event: ProgressEvent): void
{
var file:FileReference = FileReference(event.target);
var percentLoaded:Number=event.bytesLoaded/event.bytesTotal*100;
trace("loaded: "+percentLoaded+"%");
