I'm wondering if this is technically a proxy model, or rather a QAbstractListModel? Its content is not representing cells in the source model after all, which mapTo/FromSource assumes I think. It works in the example as you implement the entire QAIM interface needed for it, so the mapping functions are probably not even called, until the source model changes, or you add a selection model on top.
