openUI5 fileUploader status after upload

[Flavio]

Hi Experts,

I've taken the fileUploader Complex sample from the documentation, here, and having added an extra Input control in the view, how could I check that the upload was successful and then set the uploaded filename into the added Input control?

I was checking the Controller.controller.js code and the handleCompleteUpload function:

sap.ui.define(['sap/m/MessageToast','sap/ui/core/mvc/Controller'],
    function(MessageToast, Controller) {
    "use strict";

    return Controller.extend("sap.ui.unified.sample.FileUploaderComplex.Controller", {
        handleUploadComplete: function(oEvent) {
            var sResponse = oEvent.getParameter("response"),
                iHttpStatusCode = parseInt(/\d{3}/.exec(sResponse)[0]),
                sMessage;

            if (sResponse) {
                sMessage = iHttpStatusCode === 200 ? sResponse + " (Upload Success)" : sResponse + " (Upload Error)";
                MessageToast.show(sMessage);
            }
        },

and noticed in debugging that the sResponse is undefined;

while checking the doc, it says

has to be put within the "body" tags of the response document of the 
iFrame. It can consist of a return code and an optional message. This 
does not work in cross-domain scenarios.

is there any alternative method to check a successful upload?

Many thanks for any help about this

With Best Regards,

Flavio
