Sortable Tree Component

Is there a Vaadin component in the works to act as a sortable tree which functions like the jQuery example at the following link:

I didn’t find anything like this in the Vaadin Sampler and was wondering if this will be coming in a future release.

Thanks!

There might be something coming in 6.3
