Ext JS tree, childNodes empty before I expand root node (Load full tree structure)

I load FULL tree structure at first time.

var tree = new Ext.tree.TreePanel({
    title   : 'Simple Tree',
    width   : 300,
    height  : 300,
    root    : new Ext.tree.AsyncTreeNode({
        children : [
            { text :  'one',    leaf : true },
            { text :  'two',    leaf : true },
            { text :  'three',  leaf : true }
        ]
    })
});
Ext.onReady(function(){
    tree.render(Ext.getBody());
});

and try this..

treePanel.root.childNodes // []

But after I expand root node and try again

treePanel.root.childNodes // [obj, obj, obj]

Can I get childNodes without expand root node ?

It appears that childNodes is only populated with actual elements. Before you expand that node they are not needed.

What you are looking for is treePanel.root.attributes.children. That has three elements in it.
