XML and sound files are not loaded in PhoneGap build, iOS.

[Trost123]

The problem:
Running my game on IPhone 5 (IOS 10.2), wrapped with Cordova - no error, images load fine, but sounds and XML files don't trigger "fileload" event.
Result: my game works with no error, but has no sounds and no texts (I use createjsbitmaptext, which needs to load xml file to work).

Additional info:
Note that the same game works perfectly in Safari on the same device.
This game also works fine with PhoneGap+Cordova+Crosswalk on Android.

I narrowed down the root of the problem using this piece of code:

function loadFonts() {
    window.addEventListener('error', function(e) {
        console.log("coun't load: "+  e.target.src);
        alert("coun't load: "+  e.target.src);
    }, true); //This simply displays and logs an error in case of "404, file not found".
    var fontManifest = [
        {src: "fonts/bsfGrey.png", id: "bsfGrey"},
        {src: "fonts/bsfGrey.xml", id: "bsfGrey_xml"}
        {src: "fonts/bsfTest.png", id: "bsfTest"}, //This file doesn't exist (test 404 error handler)
        {src: "fonts/bsfTest.xml", id: "bsfTest_xml"} //This file doesn't exist (test 404 error handler)
    ];
    var loader = new createjs.LoadQueue(false);
    var fontData = {};

    loader.addEventListener("fileload", fontFileLoaded);
    loader.addEventListener("complete", allFontsLoaded);
    loader.loadManifest(fontManifest);

    function fontFileLoaded(evt) {
        fontData[evt.item.id] = evt.result;
        console.log("fileLoaded:" + evt.result); //logging and alerting if file loads.
        alert("fileLoaded:" + evt.result);
    }
}

In XDK emulator, it works as expected: logs and alerts 2 times "404 not found" (for intentionally missing xml and png) and logs 2 fileload events.

On a real device I get the following output:
"fileLoaded" - for fonts/bsfGrey.png
"couldn't load:" - for sbfText.png (as expected, because there is no such file)
And that's it.
Loading fonts/bsfTest.xml should throw an error, because this file doesn't exist. But nope, no error!
And loading fonts/bsfGrey.xml should alert "fileLoaded" - but it doesn't.
WTF.

Building in Intel XKD (cloud build).
Tried targeting: IOS (8.0 or 9.0), adhoc profile, using createjs-2015.11.26.min.js

I don't know how to poke this issue any further. Any help is welcome.

Its possible that a missing file response that is not an actual 404 could be interpreted as a success. Web Audio and XML are both loaded as text, so this could explain it.

[Trost123]

That makes sense, but doesn't help me resolve the problem in any way.
I've wrapped my app using CocoonJS instead of IntelXDK and it works just fine.
So I don't have to fight this problem anymore.

I'm still willing to try finding out the cause of the problem, just out of curiosity.
Have you got an idea on what should I log, so I could further narrow down the issue?

[lannymcnie]

Without a test case, this is hard to solve. I am going to leave it open, as we should do some more investigation on preloading in PhoneGap/Cordova for the next version.

This may be a rare problem, and it doesn't bother me anymore. Feel free to close\ignore it. 👌
If someone else gets this problem and you decide to investigate, I could send you a project where I had this issue.
As for my projects - I found a workaround by using CocoonJS, so it may be not a CreateJS\Cordova issue, but something about Intel XDK. Don't know, don't wanna waste any more time on it 😄
