Question

I have my action available. Multiple people work on this application and there is a chance that the buttons are clicked at the same time. Occasionally i get the following exception, how can i fix this?

Exception

Ajax Post

_performStaticActions: function ($click) {
        var id = $click.attr("rel");
        var link = $click.attr("href");
        if (id == "")
            jMessageError("Unable to find Id, operation aborted!", $click, false, true);
        else if (link == "")
            jMessageError("Unable to find action link, operation aborted!", $click, false, true);
        else {
            jMessage("Processing request...", $click, true, false);

            //link = link + "?badEmailId=" + id;
            $.ajax({
                cache: false,
                url: link,
                type: Ajax.MethodType.POST,
                data: { badEmailId: id},
                error: function (xhr, ajaxOptions, thrownError) {
                    jMessageError(xhr.responseText, $click, false, true);
                },
                success: function (result) {
                    if (result.IsError) {
                        jMessageError(result.Message, $click, false, true);
                    } else {
                        jMessageOK(result.Message + "<br><br>Picking new item...", $click, false, false);
                        setTimeout('PaperSurveyBadEmailCleanUp._pickNewItem()', 3000);
                    }
                }
            });
        }
    }

I have taken out NoCaching attribute on ajax post actions and it seems to work. I haven’t received any errors since yesterday. Now i need to rethink about the NoCaching attribute.
