Fineuploader – ako prepojit s presenterom

Ahojte, snazim sa rozbehat fineuploader s nette, ale potreboval by som pomoc niekoho skusenejsieho. Snazil som sa opierat aj o tento navod od Martina Zlamala (http://zlml.cz/…-uploaderu-2), ale ani ten mi velmi nepomohol. Moj problem bude zrejme v nastaveni „endpointu“.

Vyzera to u mna nejak takto:

var manualUploader = new qq.FineUploader({
     element: document.getElementById('fine-uploader-manual-trigger'),
    template: 'qq-template-manual-trigger',
    request: {
        endpoint: 'uploadFiles!'
    },
    thumbnails: {
        placeholders: {
            waitingPath: '../../../www/images/placeholders/waiting-generic.png',
            notAvailablePath: '../../../www/images/placeholders/not_available-generic.png'
        }
    },
    autoUpload: false,
    debug: true
});
qq(document.getElementById("trigger-upload")).attach("click", function() {
    manualUploader.uploadStoredFiles();
});

V prezentery mam nejaku takuto metodu:

public function handleUploadFiles() {
    $uploader = new \UploadHandler();
    $uploader->allowedExtensions = array("jpeg", "jpg", "png", "gif");
    $result = $uploader->handleUpload(__DIR__ . '/../../www/uploads');
    $this->sendResponse(new Nette\Application\Responses\JsonResponse($result));
}

Problem je, ze po kliknuti na Upload suborov dostavam v console 2 errory:

"NetworkError: 500 Internal Server Error - http://localhost/bakalarska_praca/sk/application/upload/uploadFiles!"
[Fine Uploader 5.6.0] Error when attempting to parse xhr response text (JSON.parse: unexpected character at line 1 column 1 of the JSON data)
...,!0)},reset:function(){e=[],f={},g={},i={}},setStatus:function(b,c){var d=e[b].s...

Vedel by mi niekto poradit ako spravne prepojit ten endpoint s handle metodou v prezentery?
