    That ‘Spark Tree’ is based on Spark List, but ListItemRenderer is an mx component. Just don’t mix those two. Use the Spark ItemRenderer instead.

    The Spark and mx components have a completely different architecture, so try and avoid mixing them together, especially with such coupled components as Lists and their ItemRenderers. If you decide to go for the Spark component set, use it as extensively as you possibly can, except where there is no other way (like AdvancedDataGrid for instance). I suppose this was your intent in the first place, since you don’t seem to want to use mx:Tree.
