Hello, Allan.

I have pages like that http://musiclib.org/artist/Radiohead
They use last version of datatables and it is use "sAjaxSource": "/Music/ReturnTrackTable" but somethimes that request fails and doesnt return any data. How I can handle error? I want show some button when customer click on it then code try reload the sAjaxSource.

Thanks!
