title: Oracle APEX Region auto refresh internal error
body: <p>I am new to oracle apex. When trying to do the region auto refresh in APEX,  as several docs suggested, I used the below method:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
     setInterval("jQuery('#STATIC_REGION_ID').trigger('apexrefresh');", 5000);
  &lt;/script&gt;
  </code></pre>
  
  <p>Everything worked fine but after quite a long period time (maybe SSO timeout)   there are pop-up windows said "internal error".</p>
  
  <p>Can anyone give me a hand for this? Or how can i check the server log to see more details for this internal error?</p>
  
  <p>Thanks so much!</p>
