[flexcoders] Right click on Tree's item

[Pablo]

I have the Tree and ContextMenu associated with it. When I select menu item
from context menu I cant get Tree's item was right-clicked. How I can get
this Tree's item?

           import mx.controls.listClasses.*;

           private function createContextMenu():void
           {
               m = new ContextMenu();
               m.hideBuiltInItems();
               var customItemsArr:Array = new Array();
               var buy:ContextMenuItem = new ContextMenuItem("Detailed");
               buy.addEventListener("menuItemSelect", buyHandler);
               customItemsArr.push(buy);
               m.customItems = customItemsArr;
               callTree.contextMenu=m;
           }

           private function buyHandler(e:ContextMenuEvent):void
           {
               trace(e.mouseTarget);
               trace(ListBaseContentHolder(e.mouseTarget).owner);
               trace(ListBaseContentHolder(e.mouseTarget).name);
               trace(ListBaseContentHolder(e.mouseTarget).instanceIndex);
           }
