Possible bug in aLengthMenu problem on the "All" option.

Possible bug in aLengthMenu problem on the "All" option.

There are no problems when display 10, 25 and 50 records.
But when choosing -1 or All, I see two problems/issues.

1. At the bottom, it will display "Showing 1 to -1 of 56 entries".
2. 50 records out of 56 are displayed and the First/Previous/Next/Last buttons are grayed out.

I'm using version 1.7.0 and below is the code.

jQuery().ready(function() {
jQuery('.appliance-list').dataTable({
aaSorting: [[ 3, "asc" ]],
aLengthMenu: [[10, 25, 50, -1], [10, 25, 50, "All"]],
bProcessing: true,
bServerSide: true,
sAjaxSource: '%getUrl',
bJQueryUI: true,
sPaginationType: 'full_numbers',
iDisplayStart: 0,
iDisplayLength: 50,
bRetrieve: true,
bAutoWidth: false,
aoColumns: [
{ sWidth: '10px', bSearchable: false },
{ bSearchable: false, bVisible: false },
null,
null,
{ sWidth: '50px' },
{ sWidth: '50px' },
{ sWidth: '150px' },
{ sWidth: '50px' },
{ sWidth: '50px' },
{ sWidth: '50px' },
{ sWidth: '50px' },
{ sWidth: '70px', bSearchable: false, bSortable: false }
],
fnRowCallback: function( nRow, aData, iDisplayIndex ) {
jQuery('td:eq(0)', nRow).html('');
if ( aData[7] == 1) {
jQuery('td:eq(6)', nRow).html( '' );
} else {
jQuery('td:eq(6)', nRow).html( '' );
}
if ( aData[8] == 1) {
jQuery('td:eq(7)', nRow).html( '' );
} else {
jQuery('td:eq(7)', nRow).html( '' );
}
if ( aData[9] == 1) {
jQuery('td:eq(8)', nRow).html( '' );
} else {
jQuery('td:eq(8)', nRow).html( '' );
}
jQuery('td:eq(10)', nRow).addClass('actions');
return nRow;
},
fnServerData: function ( url, data, callback ) {
jQuery.ajax({
"url": url,
"data": data,
"success": callback,
"dataType": "json",
"cache": false,
"error": function (xhr) {
if (!xhr || xhr.status != 401) {
alert( "DataTables warning: JSON data from server failed to load or be parsed. "+
"This is most likely to be caused by a JSON formatting error." );
} else {
alert('Your session expired !');
window.location.href = '%loginUrl';
}
}
});
}
});
// remove icon click
jQuery('.appliance-list a.remove').live('click', function() {
return confirm('%confirmText');
});
// all checkbox support
jQuery('input[type="checkbox"][id="all"]').click(function(ev) {
var t = jQuery(this);
if (t.attr('checked')) {
jQuery('input[type="checkbox"][id!="all"]').attr('checked', 'checked');
} else {
jQuery('input[type="checkbox"][id!="all"]').removeAttr('checked');
}
ev.stopPropagation();
});
jQuery('a#batch').click(function() {
var list = jQuery('input[type="checkbox"][id!="all"]:checked');
if (list.length) {
var applianceList = [];
list.each(function(idx, item) {
applianceList.push(item.name);
});
jQuery.post('%batchIdUrl', {applianceList: applianceList}, function(data, status, xhr) {
if (data.message) {
alert(data.message);
} else if (data.setId) {
redirect('%redirectUrl' + '/index/set_id/' + data.setId);
} else {
alert('An error occured while getting set id');
}
}, 'json');
} else {
alert('%selected');
}
return false;
});
});

    I've just tried this:

    [code]
    $(document).ready(function() {
    $('#example').dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    "sAjaxSource": "../examples_support/server_processing.php",
    "aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
    iDisplayStart: 0,
    iDisplayLength: 50
    } );
    } );
    [/code]
    and it seems to work as expect for me. I don't think there has been a bug found/fixed in aLengthMenu since 1.7.0 but I could be wrong - it would be worth upgrading to 1.7.6 and seeing if the situation changes. Failing that, can you give us a link please? I'm wonder want gets sent to / from the server on the -1 request.

    I believe what you updated is the server_side.html from the examples directory. I tried updating the example but I get a JSON format error. If I leave the server_side.html program as it is, I also still get the JSON error.

    To answer your question with regards to the link, I can provide a link because the application is internal and not available online.

    Can I request for an example here in the DataTables example that shows the "All" option?

    And how do I eliminate the -1 at the bottom of the grid?
    It shows "Showing 1 to -1 of 56 entries".

    Here is an example: http://datatables.net/dev/server_side_aLengthMenu.html - the 'showing...' is correct in this example as well, so I'm not sure where the difference is. Perhaps looking at the difference between the JSON response would be instructive.
