Tree node edit

Question

First, sorry for my English.
It is necessary to rename a treenode by selecting of a
menuitem from the contextual menu like to rename folder in Windows
explorer.
Did so:
1.) Last used treenode:
(- Tree in MXML)
<mx:Tree id="computerTree" width="100%" height="100%"
labelField="@label" showRoot="true"
dataProvider="{treeData}"
contextMenu="{treeMenu}"
itemRollOver="SetLastTreeItem(event)"
editable="false"
itemEditBeginning="Tree_itemEditBeginning(event)"/>
(- in ActionScript)
public function SetLastTreeItem(event:ListEvent):void
lastTreeItem = event.itemRenderer.data as XML;
2.) eventListener when ContextMenu item "rename" selected:
public function
ContextMenu_SelectItemRename(event:ContextMenuEvent):void
var y:int;
y=computerTree.getItemIndex(lastTreeItem);
tree.editedItemPosition={columnIndex:0, rowIndex:y};
tree.createItemEditor(0,y);
But that didn't work:
- itemEditor appears in necessary position, but empty.
- When itemEditor is closed there is an error in List.as.
(TypeError: Error #1009: Cannot access a property or method
of a null object reference.
at
mx.controls::List/endEdit()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\controls\Li st.as:2174]
at
mx.controls::List/editorKeyDownHandler()[E:\dev\3.0.x\frameworks\projects\framework\src\m x\controls\List.as:2444])
May be someone knows the ways to rename a treenode by
selecting of a menuitem from the contextual menu, not by
mouseClick?
In adobe manual I has read:
"To create an editor at other times, set the
editedItemPosition property to generate the itemEditBegin event"
But this event does not come.
