title: Problems with remote shared objects Fms Flex 4
body: <p>I'm trying to develop an application where simultaneous users can interact and i need to have a persistent remote shared object with the list of users currently in session.
  When a new user enter in the session he get the server's object with the list. That list was supose to have all the others users in session but is undefined.  </p>
  
  <p>I'm doing this first:</p>
  
  <pre><code>users_so = SharedObject.getRemote("users_so", nc.uri, true);
  users_so.connect( nc );
  users_so.addEventListener( SyncEvent.SYNC, usersSyncHandler );
  </code></pre>
  
  <p>then i set property to shared object</p>
  
  <pre><code>remoteUsers = new ArrayCollection();
      remoteUsers.addItem(displayName);
      users_so.setProperty("usersID", remoteUsers);
  </code></pre>
  
  <p>and finaly i put users in the list.</p>
  
  <p>Thanks!</p>
