Haxe CreateJS loading external manifest content fails

Am trying to build an app using Haxe and CreateJS (externs). I am running into an issue with loading manifests.

Here is the code:

function loadAssets():void
{
    var _manifest:String = "assets/manifests/mymanifest.json";
    _queue = new LoadQueue(true);
    _queue.on("complete", onQueueComplete);
    _queue.on("error", onQueueError);
    _queue.loadManifest([_manifest]);
}

contents of mymanifest.json:

{
  "path" : "assets/images/main_menu/",
  "manifest" : 
  [
    {"id" : "mm_background", "src" : "background.jpg", "type":"Image"},
    {"id" : "mm_adv_off", "src" : "advanSelectOff.jpg", "type":"Image"},
    {"id" : "mm_adv_on", "src" : "advanSelectOver.jpg", "type":"Image"},
    {"id" : "mm_tech_off", "src" : "techSelectOff.jpg", "type":"Image"},
    {"id" : "mm_tech_on", "src" : "techSelectOver.jpg", "type":"Image"},
    {"id" : "mm_app_off", "src" : "appSelectOff.jpg", "type":"Image"},
    {"id" : "mm_app_on", "src" : "appSelectOver.jpg", "type":"Image"}
  ]
}

I notice that mymanifest.json gets loaded, however none of the images get loaded.

onQueueError does not trigger, so I don't think there is a typo or malformed error...

How I verified:
I look at the console in the browser, and viewed the network load... console shows no error traces or the sort. Network does not show any loads of the images...

I am fairly certain that your manifest is just getting loaded as JSON, and that there is nothing that identifies it as a manifest.

Force the manifest type

Since you are adding the manifest as an Array with one item, it just interprets it as a plain JSON file (due to the extension). To flag it as a manifest, you can include a type to indicate to PreloadJS that the JSON file is a manifest.

Example: 

_queue.loadManifest([
    {src: _manifest, type: "manifest"}
]);

OR: Pass the manifest file directly

Pass the manifest as the only argument, instead of an Array containing the manifest. If the loadManifest method receives one argument, it assumes it is either:

  1. An Array of load items (which is what your demo is doing)
  2. A manifest Object (basically the contents of your JSON, but as JavaScript)
  3. A single file path that is a manifest.

Example:

_queue.loadManifest(_manifest); // No square brackets

That should tell PreloadJS to load the JSON, parse it, check for a manifest property of the result, and load it.
