i had been created a tree like this
Code:
 tree = new Tree.TreePanel({
    el : 'tree-div',
    autoScroll : true,
    animate : true,
    enableDD : true,
    rootVisible : false,
    containerScroll : true,
    loader : new Tree.TreeLoader({
       dataUrl : 'viewmdsdata.action' (java server)
   })
 });

 // set the root node
 root = new Tree.AsyncTreeNode({
    text : 'MDS',
    draggable : true,
    id : 'source'
   });
   
 tree.setRootNode(root);
i want make some default selected node after the tree loaded.
According the API documnet. i try to use
Code:
tree.on('load', function(node){          
           root.firstChild.select();

     }
it's not work! and "load" event is called every node added.
Then i try to use "render" event but it won't called
because the AsyncTreeNode has not been expanded.

can any one help,appreciate!
