I have created list which has same road name but several separated segment. These has sorted using length of road lines (ListSorter). The list index inside () shows length order which road segment has the longest. I need to save this list index as attribute. How to make that?

If I understand correctly, you want to have the attributes of the listelements with index = 0?

You can do this using an AttributeCreator: gid = _list{0}.gid etc
