QJSValue instead of QVariantMap when passing javascript object from QML to C++

[Pieter Cardoen]

Dear

In QML, I have:

onClicked : {
                        var data = {} // javascript object
                        // code to fill the data object
                        // the setData function is to QAbstractItemModel::setData
                        __root.model.setData(currentIndex,data,SparkplugTreeModel.Value);
                    }

In C++ I get a QVariant which is automatically converted but type is "QMetaType::User". The value I got from QML has type "QJSValue".

Why is this automagically converted to QJSValue and not to QVariantMap as expected?

Thanks
Pieter
