Hi Marc,

maybe suhajdab's answer can help you:
http://forum.jquery.com/topic/making-a-diolog-box-open-another-dialog-box-why-does-it-only-work-once

P.S. In "Ajax event handler for single column change" you are using
$url; it should be url because this is not a jQuery object.

I fixed the issue and pushed to the repo. Please check that. Thank for the help. 

Regards,
Thilanka.
