I think you got this error because you tried to define your own property
x ? In this case the property x is already defined as a final property
and because of that you cannot override it.

I didn't looked into the QML Settings yet, but I think it should be vice
versa. The property alias should be in root and the real propery in
settings. This way the root.id1 would be set once settings.id1 is set
(once the setting is loaded).
