Rails spinoffs - Dec 2007 - Problem with draggables in a list with overflow:scroll set

Hi There, hoping someone out there can help.

I have the following page set up to illustrate the problem.

http://blog.odonnell.nu/problem.html

I have a list of divs in a ul, and I want to drag them over a table,
creating a new td every time one is dropped. That much is working
fine. The problem is that I expect my list to get quite long, so I set
overflow:scroll for it. As soon as I did that, the dragables started
to go under the other controls on the page (you can see this is the
example above). Take overflow:scroll out again and it works
perfectly.
I have tried with ghosting on and off, tried manually setting z index
values, but I think that overflow:scroll is somehow placing the list
in a different stacking context, and scriptaculous doesnt seem to be
able to cope.


Anyone  have any ideas?

Thanks

Sean

Definately seems stack context related, If I reverse the order of the
page so the drop area is first, it starts working. However if I then
change the ul to be absolutely or relatively positioned, the problem
comes back (slightly worse, as now the draggable dissapears under the
lists own scrollbars)
