Issues with pagination with server side datasource

Hello.

Using the examples provided, I've a table with a server side datasource.

Everything works fine: sorting, filtering and rows per page.
But paginations doesn't seem willing to work pagination controls are always disabled.
If I've set the plugin to use 'full_numbers' pagination type, I see only one page.

I can't provide a live example, but here is the jquery:

		$adminTables.dataTable({
			"bPaginate": true,
			"sPaginationType": "full_numbers",
			"aoColumns": [
				{ "sClass": "center", "bSortable": false },
				{ "sClass": "center", "bSortable": false },
				null,
				null,
				null,
				null,
				null,
				null,
				null,
				null,
				null,
				null
			],
			"bFilter": true,
			"bInfo": false,
			"bAutoWidth": true,
			"bProcessing": true,
			"bServerSide": true,
			"sAjaxSource": "<?php app_root_full_url('lib/admin/server_auctions.php', isset($_SERVER['QUERY_STRING']) ? $_SERVER['QUERY_STRING'] : false);?>"
		});

And here the returned json:

{"sEcho":5,"iTotalRecords":"3390","iTotalDisplayRecords":10,"aaData":[["...","+++","ASanFranciscoHome.com","-","850","-","-","CA","none","-","1","-"],["...","+++","LosAngeles2Go.com","-","850","-","-","CA","none","-","1","-"],["...","+++","LosAngeles4You.com","-","850","-","-","CA","none","-","1","-"],["...","+++","4LosAngelesHomes.com","-","750","-","-","CA","none","-","1","-"],["...","+++","4LosAngelesRealEstate.com","-","750","-","-","CA","none","-","1","-"],["...","+++","ALosAngelesHome.com","-","750","-","-","CA","none","-","1","-"],["...","+++","MovingSanDiegoHomes.com","-","750","-","-","CA","none","-","1","-"],["...","+++","SanJose4You.com","-","750","-","-","CA","none","-","1","-"],["...","+++","4SanAntonio.com","-","575","-","-","TX","none","-","1","-"],["...","+++","OwnLosAngelesHomes.com","-","575","-","-","CA","none","-","1","-"]]}

With Chrome's developer tools, in the network tab, I see that a call is mate to the server-side script on load and each time a sorting or a filter is done.
Pagination controls have the disabled class, as I've already written and clicking on them, of course, doesn't do anything (i.e. no calls to the server_auctions.php script).

Any hint?
