Using sAjaxSource does not fire an Ajax call

Hi

I've been struggling with this for a day now, and I can't understand why it won't work.

This is my initialization code:

var api_url = "/api/list.php?r="+resource;

$('#list-table').dataTable( {
"sAjaxSource:": api_url,
"bProcessing": true,
"bJQueryUI": true,
"bDeferRender": true,
"aoColumns": [{"mData": "pr_id64"},
{"mData": "pr_id32"},
{"mData": "pr_name"},
{"mData": "pr_flags"}]
} );



The problem is that the Ajax call to sAjaxSource is never made, unless I set bServerSide to true (which I don't want to do, as I then need to take care of all the sorting and ordering behaviour).

Can someone please help, as I'm about to douse my desk in petrol and set everything alight.
