oTable = $('#gridDashboard').dataTable({
"bJQueryUI": false,
"oLanguage": {"sUrl": "css/jquery/tabletools-pt.txt"},
"bLengthChange": false,
"bFilter": false,
"bInfo": true,
"bAutoWidth": true,
"bProcessing": false,
"bPaginate": true,
"sPaginationType": "full_numbers",
"sDom": '<"top">rt<"bottom"iflp<"clear">>'
});

$( oTable.fnGetNodes() ).click( function() {
var iPos = oTable.fnGetPosition( this );
var aData = oTable.fnGetData( iPos );
$("#txtNproj").val(aData[0]);
$("#txtNproj").attr("disabled", true);
$("#txtReferencia").val(aData[1]);
$("#txtReferencia").attr("disabled", true);
} );
} );

Can you give us a link to your production server so we can see what is happening? The nThs is null error normally occurs if you have an incorrect number of rows / cells in the body and the header. If you view source, what is the first TR of both the header and the body of the table?

You've not got a THEAD element in that structure - which I think is the problem. DataTables needs the header to be in a THEAD: http://datatables.net/usage/#prerequisites

Hi to All I figured it out, but its very strange, to make the table with tbody, and thead, i use the my_table Library extension from codeigniter wiki.

In the Developer the library works fine and generates the html table all 100% correct with the thead, tbody.

But when i pass to the production server it stop's working, the html table is not very well generate, it's strange.

So to solve my proble what i did was on the html Library from codeigniter and not the My_table exetension i added the folowing to the template:

[code]
'heading_row_start' => '',
'heading_row_end' => '',

[/code]
