well so there is a code style problem.. any advice to make this looks better instead copy-paste such long expression here and there?

Because when loading, data[modelData] can be undefined, and data[modelData][name] can be also undefined so both of them have to be checked to avoid warning in qml.

BTW, the update is working here... I know it looks like it will break property binding, but seems qml is cleverer.
