I have a BusinessBase<Road> object that declares following property

[NotUndoable()]

private static PropertyInfo<LaneList> ExitLanesProperty = RegisterProperty<LaneList>(typeof(Road), new PropertyInfo<LaneList>("ExitLanes"));

The NotUndoable attribute is not tested in FieldDataManager.CopyState. Is that on purpose? If so, why?

Properties using managed backing fields can't be marked as NotUndoable. If you have a value that should be ignored by undo, you need to use a private backing field.
