TableTools: Undefined: evaluating 'f.buttonCounter'

Please can someone help me track down this error:

TypeError: 'undefined' is not an object (evaluating 'f.buttonCounter')

The console reports the error is in TableTools.min.js and if I remove the TableTools functions, the error disappears. I have four tables in the same page and they all use exactly the same code to (except where names/IDs/vars apply to each table). Here is one example of the code:

$('#comments-today-table').addClass('data-table', 'dataTable').dataTable({
        "bJQueryUI": true,
        "sPaginationType": "full_numbers",
        "sDom": '<""l>t<"F"fp>',
        "bRetrieve": true,
        "bSort": true,
        "bAutoWidth": false,
        "aoColumns": [
            { "sWidth": "70%", "bSortable": false  },
            { "sWidth": "15%" },
            { "sWidth": "15%", "sType": "date" }
        ],
        });
var todayTable = $('#comments-today-table').dataTable();
var todayTableTools = new TableTools( todayTable, {
        "aButtons": [
                {
                    "sExtends":    "collection",
                    "sButtonText": '<i class="icon-share-alt"></i>  Export <span class="caret" />',
                    "sButtonClass": "btn",
                    "aButtons":[
                        {"sExtends": "copy", "sButtonClass": "btn btn-mini"},
                        {"sExtends": "print", "sButtonClass": "btn btn-mini"}, 
                        {"sExtends": "csv", "sButtonClass": "btn btn-mini"},
                        {"sExtends": "xls", "sButtonClass": "btn btn-mini"},
                        {"sExtends": "pdf", "sButtonClass": "btn btn-mini", "sPdfOrientation": "landscape", 
                            "sTitle": "{{myRateableItem}}, {{myProduct}}: Comments for {{today|date:'F, Y'}} - theQRust.com"
                            }
                    ]
                }
            ],
        "sSwfPath": "static/swf/copy_csv_xls_pdf.swf",
    });
$('#comments-today-table_filter').append(todayTableTools.dom.container);

I can't link to the page or post the contents to jsFiddle unfortunately, but if anyone can give me an idea as to how I can resolve this issue, I would be very grateful!
