    Description

      Copying values in QJsonObjects sometimes doesn't work:

      Working example:

          QJsonObject obj;
    obj["prop1"] = "TEST";
    qDebug() << "OBJ 1:" << obj << obj.value("prop1");
    obj["prop2"] = obj.value("prop1");
    qDebug() << "OBJ 2:" << obj;

       

      Result:

      OBJ 1: QJsonObject({"prop1":"TEST"}) QJsonValue(string, "TEST")

      OBJ 2: QJsonObject({"prop1":"TEST","prop2":"TEST"})

      Small modifications will break it:

          QJsonObject obj;
    obj["value"] = "TEST";
    qDebug() << "OBJ 1:" << obj << obj.value("value");
    obj["prop2"] = obj.value("value");
    qDebug() << "OBJ 2:" << obj;

      Result:

      OBJ 1: QJsonObject({"value":"TEST"}) QJsonValue(string, "TEST")

      OBJ 2: QJsonObject({"prop2":"","value":"TEST"})
