[Qjson-devel] Problems parsing integers

[<luk...@em...>]

Hey there,
I really like this library and it's really easy to use. Sadly somehow something doesn't want to work and I don't understand why.

I have a class called 'Message', Message contains two private QVariantMaps, one called Header, the other Data.
I exported both QVariantMaps as a Q_PROPERTY. If I serialize the class, I get a valid JSon string:

{
 "Data" :  {
  "Code" : 0,
  "Message" : "Hello, OK"
 },
 "Header" :  {
  "SubType" : "Error",
  "Type" : "Message"
 },
 "ID" : ""
}

When I try to parse it back I get the following error:
Number is out of range:  0
json_parser - syntax error found,  forcing abort, Line 1 Column 1

I don't understand what's wrong here. Code itself is typed as int. But when I type it as an enum I get the same error. So I guess the Json parser has problems with integers itself, because enums get serialized as integers too.

I serialize/parse the class like so:

            inline static Message * ConvertFromString(QString JSon, bool * parsed = 0)
            {
                QJson::Parser   parser;

                QVariant Data = parser.parse(JSon.toUtf8(), parsed);

                if(*parsed) // I know this can lead to an error
                {
                    Message * pRequest = new Message();

                    QJson::QObjectHelper::qvariant2qobject( Data.toMap(), pRequest );

                    return pRequest;
                }

                return new pimote::Message::Message();
            }

            QString ConvertToString()
            {
                QJson::Serializer   serializer;
                serializer.setDoublePrecision(2);
                serializer.setIndentMode( QJson::IndentFull );

                QVariantMap Data = QJson::QObjectHelper::qobject2qvariant(this);

                QString Converted = serializer.serialize(Data);
                qDebug() << serializer.errorMessage();

                return Converted;
            }

I see no mistake here. If I replace the int with a QString it works. But well .. I want it typed correctly.

Thanks in advance, have a great weekend!
