Take a look also at <a href="http://arraytree.learnfromsaki.com" target="_blank" rel="nofollow">ArrayTree Extension</a>. It uses data from this article.

Jozef, This worked in ExtJs 2.1. But now, in ExtJs 2.2 it seems to be broken. Do you have an update on the article?

Can't edit my previous comment. The solution is to remove loaded:true in the ASyncTreeNode config.

@edor, it is better to handle specific problems/questions on an <a href="http://extjs.com/forum" target="_blank" rel="nofollow">Ext forum</a> where other people can help you too.

Saki, You've got some great examples and are a great asset to those learning Ext. Could you please update this example so that it will correctly work with Ext 2.2. Line 61 in your js source above should be removed and it will work like a charm again.

Why the tree displayed only shows "Tree Root", no children??? Thanks!

I use ext 2.2.1, but only display the "Tree Root", no children. What's the problem?

Hi, there is a posibility to put initially children:[], and then in a such event like render of treepanel or TreeLoader, call the load of children array? Thanks
