title: how is hot reload supposed to work in react native?
body: <p>Hot Reloading is out now but I am having lots of problems getting it to work.</p>
  
  <p>At first I had the standard <code>module.hot.accept("../reducers", () =&gt; {</code> code in my redux store but that was causing problems. After commenting that code out I started getting <code>Cannot read property 'length' of undefined</code>.</p>
  
  <p>I created a new project <code>react-native init test</code> and I get the same error every time a file is changed.</p>
  
  <pre><code>ExceptionsManager.js:61 Cannot read property 'length' of undefined
  </code></pre>
  
  <p>Is there something that needs to be done in the project to make hot reloading work?</p>
  
  <p><strong>Update</strong></p>
  
  <p>This is still undocumented and causing more problems than its worth. For now I am using redux-persist with live reloading.</p>
