MVC 3 jQuery UI autocomplete not displaying the results

I have searched many times and find examples which match my code structure perfect. Yet I am not getting the results from my ajax to display on the input box.

I get results from the POST that have been evaulated with firebug and everything looks great.

Here is the javascript im using.

<script typ开发者_C百科e="text/javascript" language="javascript">
$(function () {

    $("input.FamousPerson-List").autocomplete({
        source: function (request, response) {
            $.ajax({
                url: "/FamousPeople/FPPAutoComplete",
                type: "POST",
                dataType: "json",
                data: {
                    searchText: request.term,
                    maxResults: 12
                },
                success: function (data) {
                    response($.map(data, function (item) {
                        return {
                            value: item.DisplayName
                        }
                    }))
                }
            });
        }
    });

});

Here is a link of the actual code I am using on the web.AutoCompleteTesting Type just about any letter in one of the boxes below to invoke it.

Thanks.

If you look closely at the request being sent up, you'll notice that a callback parameter is being added. Weird, right? Since you're doing a local AJAX post, not a cross-domain (JSONP) one.

I noticed that your project includes jQuery Validate. According to this answer to a question dealing with a similar problem (performing a JSONP request instead of a normal JSON request even though you asked for one), it's a known issue in jQuery validate.

Judging by the other answer, you can change your version of jQuery or perhaps use a patched version of jQuery validate (found here).
