TableTools click on Print: sets length = -1 causing an ajax error

Terradon

I have added TableTools to my DataTable, looks well of course, but my first try to click on the Print button cause an ajax error. Looking at Firebug, I see lenght is set to a value of -1. Which of course results in an ajax error due to a negative limit in my query.

For testing : when serverside correcting $_GET['length'] to 10, it works fine.
Why is length set to -1 and how can i change this to the present length of my table?

My code for implementing TableTools

$("#mijnlogboek").DataTable({
        "processing": true,
        "serverSide": true,
        "lengthMenu": [[10,50,200,500,-1], [10,50,200,500,"Alles"]],
        "pagingType": "full_numbers",
        language: {url: '//cdn.datatables.net/plug-ins/f2c75b7247b/i18n/Dutch.json'},
        "order": [[ 0, "desc" ]],
        "ajax": "jq_datatables/mijnlogboek.php?playerID='.$_SESSION['playerID'].'",
        "dom": \'T<"clear">lfrtip\',
        "tableTools": {
            "sSwfPath": "jq_datatables/extentions/TableTools/swf/copy_csv_xls_pdf.swf" 
        }
    })

One problem found: sSwfPath typo.
changed extentions to extensions :)

So everything works now, except: PRINT sents an ajaxcall with value for length = -1
tried after changing rows to 50, still -1 is being sent as value for length.

other strange side-effect: i have got 2 selects for changing amount of rows, both works

anyone any idea? I am desperade now :(

The side-effect of displaying the select rows twice is gone now, typo with clear.

Last remaining error: Parameter length is set to -1 (negative 1 ????).

After one week i have almost reached the finish, so please??
