title: Create a simple TreeStore without using a model - Sencha Touch
body: <p>I'm trying to create a simple TreeStore without model, here is what I do :</p>
  
  <pre><code>var store = new Ext.data.TreeStore({
      fields: ['name', 'area', 'children'],
      data: {
          name: 'Budget',
          area: 1,
          children: [{
              name: 'Defense',
              area: 0.5,
              children: []
          }, {
              name: 'Education',
              area: 0.3,
              children: []
          }, {
              name: 'Debt',
              area: 0.2,
              children: []
          }]
      }
  });
  </code></pre>
  
  <p>But I get a <code>Uncaught TypeError: Cannot call method 'getReader' of undefined</code>, can someone tell me what I am missing ?</p>
  
  <p>Thanks</p>
