Hi,
I'm having some problems figuring out how to organise data pulled off XML in cells within a
container. I'm sure this should be a basic thing in AS3, but my head's fried.. can anyone help?
Basically an array if fed to callThumbs() which iterates through it and compares the entries with preloaded XML _my_images. If match is found, it's sent to processXML which loads all relevant info and loads a .jpg thumbnail. All this is then fed to createCell which creates a specific cell with position values depending on x_counter and y_counter values (4 cells in a row) and adds the cell into a
container _container_mc.
The Problem: This all works fine and looks fine, the problem is that the cells within the
container do not display in descending order. They are in random order, probably because some of the .jpg's takes longer to load etc. How do I easily organise the cells within the
container in descending order by the XML .id value? Or how do I tell Flash to wait till the thumbnail and data is loaded and the cell created and added?
Thanks guys, would really appreciate all the help!

//Flash (AS3)
function callThumbs(_my_results:Array):void { // selector = 1 for specific items, 2 for search items
var _thumb_url:XML;
for (var r:Number=0; r < _my_results.length; r++) { // iterate through results vector, compare with _my_images XML .id
for (var i:Number=0; i < _my_images.length(); i++) {
if (_my_images[i]
[email protected]() == _my_results[r]) {
_thumb_url=_my_images[i];
processXML(_thumb_url, i);
}
}
}
} // End callThumbs
function processXML(imageXML:XML, num:Number) { // Processes XML data and loads .jpg thumbnail
var _thumb_loader=new Loader();
_thumb_loader.load(new URLRequest("thumbs/thumb_sm/" + imageXML.@id + "_st.jpg"));
_thumb_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,thumbLoaded);
_thumb_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, urlNotFound);
var id:XMLList = new XMLList;
id = imageXML.@id;
var description:XMLList = new XMLList;
description = imageXML.@description;

trace("The image URL '" + String(imageXML.@id) + "' was not found.");
}
function thumbLoaded(e:Event):void {
var imageLoader:Loader = Loader(e.target.loader);
var bm:Bitmap = Bitmap(imageLoader.content);
createCell(bm, id, description, num);
adjustFooterBar(); // Adjust bottom footer
}
} // End processXML
private function createCell(_image:Bitmap, _id, _description:String, _position):void { // Creates a cell with data, add to
container
var _cell_mc = new CellTitle();
_cell_mc.initCell(_image, _id, _description, _position, x_counter, y_counter);
if (x_counter+1 < 4) {
x_counter++;
} else {
x_counter = 0;
y_counter++;
}
_container_mc.addChild(_cell_mc); // movieclip

} // End createCell
