title: Extjs Json load without Root
body: <p>My problem is the json I am getting doesn't have a root. I can get the store to load the URL and I get the JSON back but the store data is empty and nothing shows in the callback.</p>
  
  <pre><code>Json:
  [
  {
      "symbol": "GM"
  },
  {
      "symbol": "GA"
  }
  ]
  </code></pre>
  
  <p>Model and Store:</p>
  
  <pre><code>Ext.define('Symbol', {
  extend: 'Ext.data.Model',
  fields: ['symbol']
  });
  
  
  Ext.define('Doc.store.symbol', {
  extend: 'Ext.data.Store',
  model: 'Symbol',
  proxy: {
      type: 'jsonp',
      url: 'datasource/symbol',
      reader: {
          type: 'json',
          model: 'symbol'
      },
  }
  });
  </code></pre>
  
  <p>I tried removing the root as well but nothing came back in the store or the callback. My googlefu is turning up nothing good on json without root.</p>
