JSFL - Commands working in CS3, not in CS4 / CS5 (library.selectItem / library.expandFolder)

Question

Hi there,
I have a script that works perfectly fine in CS3, but does not work in CS4 and CS5.
This script is called "selectInLibrary".
You guessed it, what it does is select/highlight in library the symbols selected on the stage.
My issues are with the "library.selectItem" and "library.expandFolder" methods. They are simply not working in CS4 / CS5.
If anyone can help me with this, it would be awesome.
Code goes as follow:
function selectInLibrary(){}
var _proto_ = selectInLibrary.prototype;
_proto_.aAlreadyDone = new Array();
_proto_.DOM = fl.getDocumentDOM();
_proto_.oXMLUI;
_proto_.Init = function(){
          fl.trace("==== selectInLibrary v2.0 (for CS4) ====")
     var _aSelection;
     if (this.DOM == undefined){
          alert ("You need to open a Flash File First!");
     }else{
          this.CheckSelection();
_proto_.CheckSelection = function(){
     //     Make sure at least 1 stage element is selected
     if(this.DOM.selection.length <= 0){
          alert ("You need to Select a elements on the Stage");
     }else{
          //     Clear library selection
          this.DOM.library.selectNone();
          //     Loops through selected stage items...
          for(var i = 0; i < this.DOM.selection.length; i++){
               //     ...if selected elementType is "instance"...
               if(this.DOM.selection[i].elementType == "instance"){
                    fl.trace("Element " + this.DOM.selection[i].libraryItem.name + " already processed? " + this.ElementExist(this.DOM.selection[i].libraryItem.name));
                    //     ...if selected element has not been processed...
                    if(this.ElementExist(this.DOM.selection[i].libraryItem.name) == false){
                         fl.trace("Processing: " + this.DOM.selection[i].libraryItem.name);
                         //     ...adds selected element to array aAlreadyDone.
                         this.aAlreadyDone.push(this.DOM.selection[i].libraryItem);
                         //     ...select the item in the library.
                         this.DOM.library.selectItem(this.DOM.selection[i].libraryItem.name, false, true);
                         //     ...deploy item's folder.
                         this.deployFolder(this.DOM.selection[i].libraryItem.name);
                         fl.trace("----");
                    } else {
                    fl.trace("Skipping " + this.DOM.selection[i].libraryItem.name + ": Already processed");
                    fl.trace("----");
*     This Remove the name of a movie clip from the path 
_proto_.catPath = function(_sText){
     var _nLastPosition;
     fl.trace("catPath: " + _sText);
     for(var i = 0; i < _sText.length; i++){
          if(_sText[i] == '/'){
               _nLastPosition = i;
     fl.trace("catPath return: " + _sText.substring(0, _nLastPosition));
     return _sText.substring(0, _nLastPosition);
*     This will deploy the folder contaning the Folder
_proto_.deployFolder = function(_sText){
     fl.trace("deplyFolder: " + _sText);
     if(this.PathExist(_sText) == true){
          _sPath = this.catPath(_sText);
          fl.trace("new _sPath: " + _sPath);
          this.DOM.library.expandFolder(true, false, _sPath);
          this.deployFolder(_sPath);
*     This methode return if this is a path
_proto_.PathExist = function(_sText){
     for(var i = 0; i < _sText.length; i++){
          if(_sText[i] == '/'){
               return true;
     return false;
*     Check if the element already been modified.
_proto_.ElementExist = function(_sElement){
     _ret = false;
     for(i = 0; i < _proto_.aAlreadyDone.length; i++){
          if(_sElement == _proto_.aAlreadyDone[i]){
               _ret = true;
     return _ret;

var oSelectInLibrary = new selectInLibrary();
oSelectInLibrary.Init();

Answer 1

var succes = fl.getDocumentDOM().library.expandFolder(true,false);
// traces "success : true"
fl.trace("success : " + success);
But folder does not expand
flash 11 on a selected folder
tried with third arg as path without success
Seems like another fl.blackmagic trick
I you found something ?
