ERROR - oSettings is null

Hams

Hello,

I realize a search engine. I use DataTables to display my results.
During an initial search my table appears fine. Each table row has a link.
In a second search, my picture is always displayed correctly, but when I click on my links, I get error "oSettings is null."

Button to lunch seach
[code]

[/code]

On click, function ajax for display my results
[code]
function chargementAjax()
{
$.ajax(
{
type : "POST",
url : 'traitement.php',
data :
{
radio: $('input[name="radio"]:checked').val(),
checkZA: $('#ZA').is(":checked"),
nomEtab: $('#nom').val(),
nomResp: $('#nom_resp').val(),
Commune: $('#Commune option:selected').val(),
},

beforeSend: function()
{
$("#result").html("");
},

success: function(server_response)
{
alert ("Donnees recues");
$("#result").html(server_response);
alert ("Affichage des resultats");
}
});
}
[/code]
