asp.net mvc - jQuery Datatables Cannot read property 'length' with option bProcessing=true -

-

this works fine:

<table id="datatable">     <thead>     <tr>         <th>            title         </th>         <th>             creator         </th>         <th>            subjects         </th>         <th></th>     </tr>         </thead>  </table> <script type="text/javascript">     $(document).ready(function () {         $('#datatable').datatable({             "sdom": 'ft<"bottom clear"ip><"clear">',                 "bserverside": true,             "idisplaylength": 10,             //"bprocessing":true,             "sajaxsource": '@url.action("getmessages","performance")',             "aocolumns": [                        { "sname": "title" },                        { "sname": "creator" },                        { "sname": "subject" }]         });     }); </script>

if uncomment line "bprocessing:true" exception uncaught typeerror: cannot read property 'length' of undefined jquery.datatables.min.js:65

the code exception throw doesn me

function e(a, b) {                 if (a.ofeatures.bprocessing)                     (var c = **a.aanfeatures.r**, d = 0, = c.length; d < i; d++)                         c[d].style.visibility = b ? "visible" : "hidden";                 h(a.oinstance).trigger("processing", [a, b])             }

a.aanfeatures exist, a.aanfeatures.r undefined. action in performance controller doesn't called.

anyone?

a couple of things stand out:

there no <tbody></tbody> in table - add after </thead>.

in <thead> section have 4 <th> cells; in aocolumns section, three. how many columns ajax call returning? number of columns returned should agree.
