title: TypeError: b is undefined, if number of row in the result set is less than the pageLength
body: <p>I am using jquery datatable plugin for pagination with server side processing. The page is loading fine with data. But if entering some text in search-box, it is giving 'TypeError: b is undefined'. This happens only if the number of rows is less than the page length. For example, if page length is 10 and number of rows in the result set is 11, then it would not throw any error, but if it is 9 then it will throw error. I am using the latest version of jquery and datatable plugins</p>
  
  <p>Below is my code</p>
  
  <pre><code>$('#example').dataTable({            
          "iDisplayLength": 100,
          "pageLength": 100,
          "lengthMenu": [ 10, 25, 50, 100, 500],
         "bProcessing": true,   
          "serverSide": true,
          "ajax": {
                  "url": "/admincp/exportdata/branch",
                  "type": "POST",
                  "cache" : false,
                  "headers": { "cache-control": "no-cache" }
          },
          "columns": [
                  { "data": "code" },
                  { "data": "name" },                    
                  { "data": "action" }                            
          ]
  })
  </code></pre>
  
  <p>any help is appreciated.</p>
