What I'm expecting is that mappings would be transformed on the

I'm going in an incorrect direction?
Are you sure about the transformation? Only certain data types are supported for the C++ <-> QML data exchange, and I don't believe the one you're using is:
https://doc.qt.io/qt-5/qtqml-cppintegration-data.htmlIn other words, you may need to change the datatype / transform it somehow before giving it to QML. (Also do you want to just _read_ it from QML or also write into it? The above QML syntax looks a bit sketchy...)
