I've downloaded ext-220.127.116.11 and am trying to see the examples using the documentation app. But the tree examples are not working and there is no data visible. The tree is expanded and no nodes are visible. I tried other examples as well, but none of the tree examples are working.
Below is a sample screenshot. I tried it in Safari 5.1.1 (7534.51.22) and Chrome 15.0.874.106. Am on MacOSx Lion 10.7.2
