Help with how to refresh one region of an APEX 4 page.

Question

I have tried the options I can find to refresh a single region (classic report) on an APEX 4 page. I want the refresh to happen automatically without any input from a user (no button press, no sorting on the report or anything). Just based on a 5 second interval. Can someone help me further. It seems that I need to either use javascript or jquery. I am not sure where to put this code.
I have tried the following different methods. I put them in the Region Footer. Not sure if that is the proper place. Nothing happened when I did this.
Using: Application Express 4.0.2.00.07
<script type="text/javascript"> 
  <!-- 
    jQuery('#STATIC_ID_OF_REGION').trigger('apexrefresh');
  //-->
</script>
<script type="text/javascript"> 
  <!-- 
    setInterval( "$a_report('#REGION_ID#'.substring(1), 1, 7, 7);", 5000);
  //-->
</script>
<script type="text/javascript"> 
  <!-- 
    setInterval(function(){ $('#P4_LIST').trigger('apexrefresh'); }, 000);
  //-->
</script>Thanks.

Hi cj,
The following works for me. I just chucked the function in global function definition on the page definition.
var doIt = function(){
$('#comment_report').trigger('apexrefresh');
  setTimeout("doIt()", 5000);
}And execute on page load:
doIt();Edited by: trent on Oct 14, 2011 9:11 AM
By the way, what is the function $a_report? I can't see any documentation for it: http://download.oracle.com/docs/cd/E23903_01/doc/doc.41/e21676/javascript_api.htm#CDEEIGFH Is it a supported function?
Also in your above examples, you set the interval once, but it wouldnt recurr as you're only calling setTimeout once. http://www.w3schools.com/js/js_timing.asp
