public override function set filterFunction(f:Function):void
            throw new Error("Setting the filterFunction on RosterGroup is not allowed; Wrap it in a ListCollectionView and filter that.");


this is radicoulas, can this be fixed?  RosterGroup is ArrayCollection which is ListCollectionView I dond understand why it is neccessary to wrap RosterGroup inside another ListCollectionView that sounds extremly inefficient.
