Hello , trying to create a tree panel with a child node, I could not do it programatically. Please let me know what I am missing?

The root is an AsyncTreeNode, so it will load when expanded.

You have two options:
1. Change the root to a TreeNode so it doesn't do loading.
2. Configure the loader with clearOnLoad:false, so it doesn't clear your child node before loading.

That works.
