Hi @LuisAbreu!
I cannot confirm this. Are you sure your json file is valid? The following works for me:
============================================
Json file:
{
"className": "ShoppingCart",
"closedOn": "Fri Mar 27 15:52:13 2015",
"coupon_count": "0",
"createdOn": "Fri Mar 27 15:51:09 2015",
"list": [
{
"_className": "Product",
"discount": "0",
"fromyoubeep": "1",
"has_alarm": 0,
"id": "5601151333457",
"intendedQuantity": 0,
"isReady": "1",
"isUnknown": "0",
"loyaltyCredit": -1,
"min_age": 0,
"name": "Sumo Compal Cl<C3><A1>ssico Tutti-Fruti 1lt",
"userCreated": "0",
"weight": "0"
},
{
"_className": "Product",
"fromyoubeep": "0",
"has_alarm": 0,
"id": "",
"intendedQuantity": 0,
"isReady": "1",
"isUnknown": "0",
"userCreated": "0",
"weight": "0"
}
],
"loyaltyCard": {
"_className": "LoyaltyCard",
"barcode": "2446037038353",
"barcodeType": "EAN13",
"discount": "0",
"fromyoubeep": "1",
"has_alarm": 0,
"id": "2446037038353",
"intendedQuantity": 0,
"isReady": "1",
"isUnknown": "0",
"loyaltyCredit": 0,
"min_age": 0,

"price": "0",
"product_id": "-1",
"quantity": "0",
"quantityValidated": "0",
"state": "0",
"type": 1,
"userCreated": "0",
"weight": "0"
},
"mobile_checkout": "1"
}
============================================
C++ code:
QFile file("/home/pw/file.json");
if (!file.open(QIODevice::ReadOnly)) {
qDebug() << "file error";
return;
}
const QByteArray ba = file.readAll();
file.close();
QJsonParseError err;
QJsonDocument doc = QJsonDocument::fromJson(ba, &err);
qDebug() << err.errorString();
qDebug() << err.offset;
QJsonObject sett2 = doc.object();
qDebug() << sett2.isEmpty();
QJsonObject sett3 = sett2.value(QString("loyaltyCard")).toObject();
qDebug() << sett3.isEmpty();
QJsonValue sett4 = sett3.value(QString("barcode"));
qDebug() << sett4.toString();
============================================
Cheers!
