title: extjs grid filter example not loading data
body: <p>I'm attempting to learn a bit more about out how grid filtering works in Extjs.</p>
  
  <p>I'm using the example that comes with the JS 4 download, i.e.</p>
  
  <p><a href="http://docs.sencha.com/ext-js/4-0/#!/example/grid-filtering/grid-filter-local.html" rel="nofollow">http://docs.sencha.com/ext-js/4-0/#!/example/grid-filtering/grid-filter-local.html</a></p>
  
  <p>I can run it on my local server such that it displays the grid outline (with filter options in the column headers), but no data gets loaded at all. I was hoping that I could just use the local flag with the accompanying JSON file without the need to get involved with the SQLlite aspects, for a start.</p>
  
  <p>I can't figure out why the JSON data isn't loading though. Any help, hints or tips would be much appreciated. I've spent ages on this, looking at other examples, both via here, Google and the Sencha website.</p>
