title: Empty error message with jQuery.jTable
body: <p>I'm having problems with the <a href="http://jtable.org/" rel="nofollow noreferrer">jquery.jtable.js</a> plugin.</p>
  
  <p><strong>My problem:</strong></p>
  
  <p>jTable continues to post this empty modal error message:</p>
  
  <p><img src="https://i.stack.imgur.com/m0Kv3.png" alt="jTable error message on load"></p>
  
  <p>For your information:</p>
  
  <ul>
  <li>I'm using <a href="http://nancyfx.org/" rel="nofollow noreferrer">NancyFX</a> for my backend. </li>
  <li>There are no 404s, everything is 200 OK</li>
  <li>The objects I'm returning are plain POCOs, no proxies or anything of that nature</li>
  </ul>
  
  <p>This is my HTML:</p>
  
  <pre><code>&lt;!-- in the header --&gt;
  &lt;script src="~/Scripts/jquery-1.9.1.js"&gt;&lt;/script&gt;
  &lt;link href="~/Content/themes/base/jquery-ui.css" rel="stylesheet" /&gt;
  &lt;link href="~/Scripts/jtable/themes/basic/jtable_basic.min.css" rel="stylesheet" /&gt;
  &lt;script src="~/Scripts/jtable/external/json2.min.js"&gt;&lt;/script&gt;
  &lt;script src="~/Scripts/jquery-ui-1.9.2.min.js"&gt;&lt;/script&gt;
  &lt;script src="~/Scripts/jtable/jquery.jtable.min.js"&gt;&lt;/script&gt;
  
  &lt;!-- in body --&gt;
  &lt;div id="UsersTableContainer"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I have this javascript (whithin a $(document).ready()):</p>
  
  <pre><code>$('#UsersTableContainer').jtable({
      title: 'All users',
      paging: true,
      pageSize: 10,
      sorting: true,
      defaultSorting: 'UserName ASC',
      actions: {
          listAction: '/api/backend/users/list',
      },
      fields: {
          UserName: {
              title: 'UserName',
              key: true,
              list: true,
              width: '20%',
              sorting: true
          }/* and more 
              I've tried userName and UserName - nothing works
              I've tried to map all properties and none, using a test column - nothing works */
      }
   });
   $('#UsersTableContainer').jtable('load');
  </code></pre>
  
  <p>I can see with fiddler 2 that this is sent across the line:</p>
  
  <pre><code>{
    "records": [
      {
        "userName": "user"
        /*, more properties */
      }/*, more records */
    ],
    "result": "OK",
    "message": "All OK", //tried with an without this, just to see if it pups up
    "totalRecordCount": 2
  }
  </code></pre>
