Javascript function not working in IE but in Firefox

Question

Dear fellow developers and pros, I have a huge problem with the following function. While it works perfectly in Firefox, the Internet Explorer (my special friend) doesn't interpret the code correctly. At least this is my guess. The message box appears but the UPDATE process is not carried out and the application procedure "proc_delete_mx" is not carried out either. Only the redirect works!
I need to get it to work in IE, as a lot of end users depend on the IE and are restricted to use alternative browsers.
Can you please help me on this one!??? You're my last hope as I have already tried to paste this function into several template regions. In the past it used to work for jQuery code not interpreted by the IE.
<script type="text/javascript">
  function warning1(){
    var lValue = $v('P231_CHECK_CE_STATUS');
    var pValue = $v('P231_INT_STATUS');
    if(lValue*1 > 0 && (pValue == 1 || pValue == 2 || pValue == 5 || pValue == 6 || pValue == 7 ) )
      $('#dialogwarning').dialog('open');
else
      doSubmit('UPDATE');
      redirect('f?p=105:18:&APP_SESSION.::NO:');
$(function(){
  $("#dialogwarning").dialog({
    autoOpen: false,
    bgiframe: true,
     modal: true,
        width: 400,
        minWidth: 400,
        resizable: true,
     buttons:
{Speichern: function()
var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=proc_delete_mx',0);
gReturn = get.get();
get = null;
doSubmit('UPDATE');
$(this).dialog(redirect('f?p=105:18:&APP_SESSION.::NO:'));     
Abbrechen: function(){
$(this).dialog('close');
</script>
<div id="dialogwarning" title="Achtung!">

<span class="ui-icon ui-icon-alert" style="float:left; margin:0 10px 40px 0;"></span>Es liegen bereits gutachterliche Bewertungen für diesen LRT vor.

Answer 1

Okay, I eventually found the bug myself and was able to fix it.
The Internet Explorer 8 simply doesn't like a doSubmit followed by a straight redirect!
doSubmit('UPDATE');
           redirect("f?p=&APP_ID.:1:&SESSION.");How I solved it??
I created two custom pl/sql update procedures, which I'm calling in javascript with doSubmit.
doSubmit('UPDATE_CUSTOM1');Additionally I created two new branches directing to the desired pages and set them to be conditional.
Now the branches are taken after the request of my update procedures has been issued.
Furthermore, I have no more problems with binding page items on subsequent pages, since the branches are doing it.
Hope it helps!
