Error in grid plugin when re-initialising fancytree after destroying

[sophanox]

Fiddle here: http://jsfiddle.net/fun67w1c/

As you can see, it makes a grid instance with the plainscrollbar, then destroys it after 5 seconds and recreates.

If you try to scroll then, you'll see it results in an error in 'isViewportBottom' due to visibleNodeList being null. In the example I clear the scrollbar innerHTML and remove its events, but the bug still happens. The bug even happens if the HTML for the scrollbar is replaced entirely.

Not sure what's going on! Is the 'destroy' not clearing off something that pertains to the grid properly?

Thanks!

Does tree.redrawViewport(true) help?

Gives me the same error unfortunately.

The destroy function did not unregister the 'wheel' handler callback, which still referenced the now-dead tree instance.
