anyone know why 

```
QString Lulu ( data ); //data is a QByteArry ( from a QNetworkrequest ) 
std::stringstream streamedJson ;

   // QString Lulu ( data.data() );
    qDebug()<< "Lulu:" << Lulu; // here it views the right string

    streamedJson << Lulu.toStdString();
    qDebug() << "streamedJson: "<< streamedJson ; // here it views 0x7fffc9d46568

```

doesn't works ? 
why it dont view the String here ? 
finally i would parse it and give the parsed string out 

```
boost::property_tree::ptree propertyTree;
            try
            {
                boost::property_tree::json_parser::read_json(streamedJson, propertyTree);
            }
catch(boost::property_tree::json_parser::json_parser_error& ex)
       {
           qDebug() << "ex: "<< ex.what(); // this and Lulu views the same (unparsed) string 
           qDebug ("propertyree error");
       }

```

at the moment it only views "propertyree error". but it should print the parsed String in my console
