Depends on what you class a duplication.
With a Model / View you might say that is duplication, in that you have a structure for the model, and a similar structure to view the model.
as far as I'm concerned, I need a model to describe the Tree of nodes, and happen to use the TreeView gadget to view that model.
Anything I do to the "model" (like adding / moving nodes) I then reflect those changes in the TreeView...
Seems to work ok? :-)
(I'm sure there are better ways to do these things)
