Asynchronous update of Flash chart error in IE

Question

Hi gurus,
I had a post a while ago about an update command for a flash chart:
[Asynchronous update of flash chart when select list value changes|http://forums.oracle.com/forums/thread.jspa?messageID=3491745]
The goal was when I clicked a button or changed a select list the flash chart should update. Here is the command to update the flash chart:
apex_RefreshChart ($v('pFlowStepId'), $v('Pxx_REGION_ID').substr(1), navigator.language );This worked really well in Firefox but IE always created an error:

I found out that IE used another function to get the client language. I fixed that but an error still occurs:

//check the Browser type to set the right browser language
function fnc_checkBrowserLanguage()
var nav_lng="en"; //default language string

if(navigator.browserLanguage)nav_lng=navigator.userLanguage;

if(window.navigator.language)nav_lng=window.navigator.language;
return nav_lng;
// return 'en-us';
function fnc_setTablespaceItem (pItem)
  var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=dummy',0);
  get.add(pItem,$x(pItem).value)
  gReturn = get.get();
// alert('Item '+pItem+' Session State set to '+$x(pItem).value+'!');
  var v_flow_id = $v('pFlowStepId');
  var v_region_id = new String($v('P1_REGION_ID_TU').substr(1));
  var v_browser_lang = fnc_checkBrowserLanguage();
  //alert(v_flow_id);
  //alert(v_region_id);
  //alert(v_browser_lang);
  var vOriginal_apex_RefreshChart = apex_RefreshChart;
  apex_RefreshChart = function(v_flow_id,v_region_id,v_browser_lang)
    vOriginal_apex_RefreshChart(v_flow_id, v_region_id, v_browser_lang);
  apex_RefreshChart(v_flow_id, v_region_id, v_browser_lang);
  get = null;
}If I set the alert boxed all variables have a value. Firefox works well. And I have no idea what I could do next???

I just found out that the original time based flash update option creates the same error I get all the time. It can be configured under:
Chart attributes > Refresh: Asynchronous Update = YES and Update Interval (Seconds) = 10
Error: (line 49) (JScript - script block):
function __flash__addCallback(instance, name) {
  instance[name] = function () {
    return eval(instance.CallFunction("<invoke name=\""+name+"\" returntype=\"javascript\">" + __flash__argumentsToXML(arguments,0) + "</invoke>"));
  }By the way I use the newest APEX version: "Application Express 3.2.1.00.10"
Seems more like a general error? Everybody should be able to rebuild this under IE 8 or IE 7. I use IE8!
Created source code:
&lt;script type="text/javascript" language="javascript">
function chart_r2258227549390282_InitRefresh(pNow) {
  setTimeout("chart_r2258227549390282_InitRefresh(true)",10000);
  if (pNow){apex_RefreshChart (1, '2258227549390282', 'de');}
apex_SWFFormFix('c2258227549390282');
&lt;/script>It still works well with Firefox.
