DataTables "LENGTH" and "SEARCH" in $GET data missing

tomekkicaj700

Hi!

I'm using the following init:

$('#PlaceHolder').dataTable(
    {
        "dom": 'T<"clear">lfrtip',
        "processing": true,
        "serverSide": true,
        "bDestroy"  : true,
        "iDisplayLength":10,
        "ajax": "../scripts/myDataTables_server_processing.php",
        "order": [[ 0, "desc" ]],
        "aoColumns":
            [
                {"bSortable": false},
                null,null,null,null,null,null,null,null,null,null,null,null,
                {"bSortable": false},
                {"bSortable": false},
                {"bSortable": false}
            ],
        "tableTools":
        {
            "sSwfPath": "../resources/DataTables/extensions/TableTools/swf/copy_csv_xls_pdf.swf",
            "sRowSelect": "multi",
            "aButtons":
                [

                    {
                        "sExtends":    "copy",
                        "bSelectedOnly": "true"
                    },
                    // "print",
                    {
                        "sExtends":    "collection",
                        "sButtonText": "Save",
                        "aButtons":
                            [
                                {
                                    "sExtends":    "csv",
                                    "bSelectedOnly": "true"
                                },
                                {
                                    "sExtends":    "xls",
                                    "bSelectedOnly": "true"
                                },
                                {
                                    "sExtends":    "pdf",
                                    "bSelectedOnly": "true",
                                    "sPdfOrientation": "landscape",
                                    "sTitle": "Raport zgrzewania"
                                }
                            ]
                    }
                ]
        }

    }

).fnClearTable();

when ajax GET is called for data the header looks ok:

but when I output $GET in " myDataTables_server_processing.php" the last parameter that is available is "start" and no "length", nor "search" are available ("not set") as if the GET url data was truncated.

What can be the reason for this?

Thanks
