title: Highstock: Property 'firePointEvent' of object #<Object> is not a function
body: <p>When fire a click on a serie, I get the next error : <strong>Uncaught TypeError: Property 'firePointEvent' of object # is not a function</strong>.</p>
  
  <p>In Highstock.js v1.3.1 (2013-04-15) on line 9575 :</p>
  
  <pre><code>// the series click event
  fireEvent(hoverPoint.series, 'click', extend(e, {
      point: hoverPoint
  }));
  </code></pre>
  
  <p>Until there, <code>hoverPoint</code> exist and have real values, but don't have yet <code>firePointEvent</code> method.</p>
  
  <pre><code>// the point click event
  hoverPoint.firePointEvent('click', e);
  </code></pre>
  
  <p>On this next line, <code>hoverPoint</code> still exist and do have a <code>firePointEvent</code> method, but all its attributes are null. So it throws the error :/</p>
  
  <p>What's the problem here?</p>
