fnDraw not calling the Ajax source

tsabz

Hello,

First of all, thanks for your plugin, it's very nice, usefull and quite easy to approach.

My bug is the following : I'm drawing a table with a delete button on each row. My delete button is binded to an Ajax call that deletes my data in database, and then I want to reload manually the data on my table.

Here's how I defined my table :

[code]
var oTable = $('#dt_groups').dataTable({
'bServerside': true,
'sAjaxSource': 'my_page?group='+group,
'sAjaxDataProp': "",
'aoColumns':[
{
'mData':'column_1',
'sWidth': '20%',
},{
'mData':'column_2',
'sWidth': '50%',
},{
'mData':'column_3',
'sWidth': '10%',
},{
'mData':'column_4',
'sWidth': '10%',
},{
'mData': null,
'mRender':function(row, type, full) {
return '';
},
'sWidth': '5%',
},{
'mData': null,
'mRender':function(row, type, full) {
return '';
},
'sWidth': '5%',
}
],
"aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
'iDisplayLength':25,
'fnCreatedRow': function(nRow, aData, iDataIndex) {
$(nRow).attr('data-lineid', aData['id']);
$(nRow).attr('id', 'groups');
$(nRow).attr('data-groupid', aData['id_group']);
},
});
[/code]

And here's my Ajax call to delete the row :

[code]
$('#delete_group').live('click', function() {
var id_group = $(this).closest('tr').attr('data-groupid');
$.ajax({
type: 'POST',
url: 'my_page.php',
data: 'method=delete&id_group='+id_group,
success:function(data) {
$('#dt_groups').dataTable()._fnDraw();
}
});
});
[/code]

The thing is, that the fnDraw function doesn't actually reload the data, and in the FF's console, I can' t see any GET call to my Ajax datasource.

I tried with _fnAjaxUpdate() instead of _fnDraw() and there I can see my ajax call, but then I have this js error :

[code]TypeError: aData is undefined[/code]

I guess it has something to do with [code]'sAjaxDataProp': ""[/code] defined in my dataTable but I'm not that sure.

Any clue ?
