Using sspublisher.recipientIDs to specify viewers of screen sharing

Question

Dear colleagues,
In the documentation here: http://livedocs.adobe.com/labs/acrobatcom/com/adobe/rtc/collaboration/ScreenSharePublisher .html
i fount this lines of code:
//this is optional
  var userlist:ArrayCollection = connectSession.userManager.userCollection;
  var recipientIDs:Array = new Array();
  for(var i:int=0; i<userlist.length; i++){
    recipientIDs.push((userlist.getItemAt(i) as UserDescriptor).userID);
     // this is optional, default is everyone in the room can see the screen share
  sspublisher.recipientIDs = recipientIDs;
I'm trying to use it, but get "undefined property recipientIDs" in the last line. Would you please give an advise how should I specify the users that can view the screen sharing?

Hi there,
Wow, this is a strange bug - the whole system for recipientIDs is set up in
the code, but the public property isn't exposed. Thanks for reporting this,
we'll get a fix in.
  In the meantime, you should be able to work around this issue by
subclassing the WebcamPublisher and adding the following methods :
public function set recipientIDs(p_ids:Array):void
   recipientIDs = pids;
public function get recipientIDs():Array
   return _recipientIDs;
Note that if your publisher is already publishing, you'll need to stop
publishing and start it again for this to take effect.
  thanks again for taking the time to post this. We'll have this corrected
in an upcoming release, and your feedback really helps.
