Connection Problems Between iChat 3 and iChat 4 Workaround

Question

Maybe this info will help others:
iChat 4/Leopard users must initiate video chat to iChat 3/Tiger users:
I have discovered that if an iChat 4/Leopard user initiates the video chat to an iChat3/Tiger user, it works, but if the iChat3/Tiger user initiates the video chat with an iChat 4/Leopard user it fails with a message saying that the receiver declined the invitation (even if the receiver tried to accept). This happens on a LAN as well as across the Internet.
Likewise, to make conference video chats, make sure the iChat 4/Leopard user initiates, then adds the other parties.
This post is NOT about iChat Server, although the problem occurs there too. If you are using iChat Server (part of OSX Server) see http://discussions.apple.com/thread.jspa?messageID=5995966 ).
Hope this helps.

Hey.
I found how to work around combatible problems between 1.3 and 1.4. For user, that want to save thier DynamicTree.java (http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/index.html)
Use follow code (I using Externalizable):
  protected DefaultMutableTreeNode rootNode=null;
  protected DefaultTreeModel treeModel=null;
  public void writeExternal(ObjectOutput stream) throws IOException
  { stream.writeUTF(rootNode.toString());
    Vector values = new Vector();
    Object root = treeModel.getRoot();
    // Save the root, if its Serializable.
    if(root != null && root instanceof Serializable)
    { values.addElement("root");
      values.addElement(root);
    stream.writeObject(values);
  public void readExternal(ObjectInput stream) throws IOException
  { thisModel.removeAll();
    thisModel.setVisible(false);
    try
    { String title=stream.readUTF();
      rootNode = new DefaultMutableTreeNode(title);
      Vector values = (Vector)stream.readObject();
      int indexCounter = 0;
      int maxCounter = values.size();
      treeModel = new DefaultTreeModel(rootNode);
      if(indexCounter < maxCounter && values.elementAt(indexCounter).equals("root"))
      { TreeNode root = (TreeNode)values.elementAt(++indexCounter);
        treeModel = new DefaultTreeModel(root);
        indexCounter++;
      // kode for setting the tree start here
    catch (ClassNotFoundException e) {}
  }Hope, this is to use :-)
