Finder's listview

How does Finder implement it's Listview? Can I do the same thing in my
application?

I tried:

An NSOutlineView with a non-displaying root data-source. This failed to
expand it's child items correctly.

A custom NSCell which crashed deallocating it's embedded NSOutlineView.

I'm missing something obvious here.
