I can look at fixing this later today. However Serkan, if you want to confirm this you should be able to easily test it by making the change above in your js-debug output to see if it works. If you can confirm that, it would be helpful. (js-release won't work until this is addressed) I made the changes in the js but could not make it work. I prepared a simple example, I made the changes on this small sample but even the sample did not work. Also colud not make it to load tree data dynamically.
