On Demand AJAX No Response?

Question

Have a weird issue. We switched a web server (Oracle 10G App Server) over from our sandbox Apex area to our new development database which runs 3.2.0.00.27. I imported a few test applications from the sandbox which worked without issues because we used it in a customer demo. Anyway they are fairly simple Ajax calls to populate a select list but it does not seem to be firing correctly that I can tell. I definitely shortened up the query in the on-demand process so that it was simple but the real query didnt work either. Is this network related or do I have a bug somewhere in the code? It seems like none of the AJAX stuff that used to work in the other database is functioning any more.
I called the on demand process by itself in the URL and it returned:
<select>
<option value="1">TEST</option>
</select>So I'm sure it should actually be functioning but the select list is not populating. I looked in firebug and it is POSTing and I can see a parameter being passed, but I'm getting no response.
p_flow_id:102
p_flow_step_id:0
p_instance:883066291548100
p_request:APPLICATION_PROCESS=populate_select
x01:IM PASSING THISI have items P13_X3 (text field) and P13_X4 (select list). onblur for P13_X3 is onblur="populate_select(this, 'P13_X4');"
Here is the javascript and on-demand:
<script language="JavaScript1.1" type="text/javascript">
function populate_select(pThis,pSelect){
     var l_Return = null;
     var l_Select = $x(pSelect);
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=populate_select',0);
     get.addParam('x01',$v(pThis));
     gReturn = get.get('XML');
     if(gReturn && l_Select){
        var l_Count = gReturn.getElementsByTagName("option").length;
        l_Select.length = 0;
        for(var i=0;i<l_Count;i++){
            var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'),
l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
</script>
declare
  v_count number:= 0;
begin
    owa_util.mime_header('text/xml', FALSE );
    htp.p('Cache-Control: no-cache');
    htp.p('Pragma: no-cache');
    owa_util.http_header_close;
    htp.prn('<select>');
    for r in (select 'TEST' name,
                     1 id
                from dual
               order by 1) loop
v_count := v_count + 1;
htp.prn('<option value="' || r.id || '">' || r.name || '</option>');
end loop;
htp.prn('</select>');
end;

Hi,
The application process itself looks ok. Comparing it to an example that I use ([http://apex.oracle.com/pls/otn/f?p=20297:14]), the only difference is that I have a "data" tag around the "select" tag - I don't think that this is necessarily required, though. Otherwise, it matches exactly (apart from the SQL statement itself, of course!).
Two suggestions:
1 - Change either the process name or the javascript function name so that they are different
2 - Change the 0 in the last parameter of the Ajax call to the actual page number
Otherwise, I'll have another look at the javascript again
