Problem dynamically setting row background color in a report

Question

Hi guys,
I want a PPR Classic SQL Report to dynamically show a background color depending on what value is stored in the column of the record.
To illustrate what I've tried consider the following:
1. I created a PPR Report on DEPT (this is the report I want to use with record backgrounds)
2. I created a PPR javascript call that I trigger somewhere in the page
function refreshReport(pField, pValue){
  var region = $v('P2_DEPT_RID');
  var link ='f?p=' + $v('pFlowId') + ':' + $v('pFlowStepId') + ':' + $v('pInstance') +'::::' + pField +':'+ pValue;
  html_PPR_Report_Page(this, region, link);
The updating of the report works fine by the way.
3. I changed the code in the HTML Expression of the column definition of "DNAME" of the DEPT report. I used jQuery to set the class of the <tr> element of the position the field is in.
This is the value I want to dynamically check on
<div id="dept_#DEPTNO#">#DNAME#</div>
<SCRIPT type=text/javascript>
$('#dept_#DEPTNO#').parent().parent().children().removeClass('t20data');
if ('#DNAME#' == 'RESEARCH'){
      $(function(){    
        $('#dept_#DEPTNO#').parent().parent().addClass('voorhaal_kan');
}else{
         $(function(){    
            $('#dept_#DEPTNO#').parent().parent().addClass('sscc_ok');
</SCRIPT>4. I created some CSS like so:
tr.voorhaal_kan{border:1px solid #AAA;border-left:none;border-top:none;background-color:#FFDD44;padding:2px 8px;}
tr.sscc_ok {border:1px solid #AAA;border-left:none;border-top:none;background-color:#CCFFCC;padding:2px 8px;}
tr.sscc_manco {border:1px solid #AAA;border-left:none;border-top:none;background-color:#FF3300;padding:2px 8px;}
tr.sscc_geel {border:1px solid #AAA;border-left:none;border-top:none;background-color:#FFFF66;padding:2px 8px;}Now the problem is, the first time I load the page, the javascript in the HTML Expression works fine! It checks the value, and colors the <tr> beautifully. But, when i Refresh the report using PPR (calling the javascript function), the report is reloaded just fine, but the javascript bit in the HTML Expression is skipped for some reason resulting with a regular background color found in "t20Standard td.t20Data" . Alerts won't fire either in the code, hence the assumption of the code skipping.
Any ideas on how this problem can be solved?

Hey Rutger,
I know you've already done a lot of work in another direction, but would it be possible for your purposes to use the SQL to do what you need. check out this link:
How to perform a conditional column format based on column value
and Conditional coloring of Database Column
I hope those may help or give you other ideas.
