[flexcoders] Tree Item by Index

[syabro]

How can I get an item, when I've an item index?
I think that
tree.selectedIndex = index;
item = tree.selectedIndex;
will be great, but is there another method?

[flexcoders] Override owner in TreeItemRenderer

[syabro]

I need a send [EMAIL PROTECTED] to an owner (tree). I've 
extend Tree class and write function Tree.setPath();

But when I tried to use this function as owner.setPath Flex says 
Call to a possibly undefined method setPath through a reference with 
static type flash.display:DisplayObjectContainer.;

How can I use this function?

package CellRenderers
{

import mx.controls.treeClasses.*;
import mx.collections.*;
import flash.ui.ContextMenu;
import flash.ui.ContextMenuItem;
import flash.ui.ContextMenuBuiltInItems;
import flash.events.ContextMenuEvent;
import flash.events.ContextMenuEvent;
import flash.events.MouseEvent;
import ed.ETree;
 

public class ETreeItemRenderer extends TreeItemRenderer
{

public function ETreeItemRenderer() 
{
super();
this.addEventListener(MouseEvent.MOUSE_OVER, 
mouseOverEvent);
}

public function mouseOverEvent(event:MouseEvent):void
{
owner.setPath([EMAIL PROTECTED]);
}   
}
}
