------------------------------------------

Solved the problem on MYFACES-2533 but now I have other different problem when using t:tree2:

> A rendered <t:tree> tree can not be collapsed or opened any more (with core 2.0).
> The nodes' command links seem to be rendered wrong.
> Example from the examples module:

>             styleClass="tree"

>             selectedNodeClass="treenodeSelected"
>             expandRoot="true">
>         </t:tree>
>     </h:form>
> tree1Backer:
> public class Tree1Backer {
>     private TreeModel treeModel;
>     public TreeModel getTreeModel() {
>         if (treeModel == null) {
>             DefaultMutableTreeNode root = new DefaultMutableTreeNode("XY");
>             DefaultMutableTreeNode a = new DefaultMutableTreeNode("A");
