Missing Hidden form fields

Hello,

I am using JBoss 4.2.1.GA with tomcat 6.0, and i am not able to figure out this
problem.

Code:

//test.jsp

if(request.getParameter( "ScreenResolutionHeight" ) == null )
{
%>
<html>
<head>
<title>Please wait one moment...</title>
</head>
<body onload='SubmitOnLoad();'>

<form method='post' id='ScreenResolutionForm'>
<input type='hidden' name='ScreenResolutionWidth' value='1024'>
<input type='hidden' name='ScreenResolutionHeight' value='768'>

<script>
function SubmitOnLoad()
{
var this_form = FindElementById( 'ScreenResolutionForm' );
this_form.ScreenResolutionWidth.value = window.screen.availWidth;
this_form.ScreenResolutionHeight.value = window.screen.availHeight;
this_form.BrowserType.value = navigator.appName;

this_form.submit();
}

function FindElementById( id )
{
if( document.getElementById )
{
return document.getElementById( id );
}
else if (document.layers)
{
return document.layers[id];
}
else if (document.all)
{
return document.all[id];
}

return undefined;
}
</script>

</body>
</html>
<%
}else {
............

After the form the submitted to itself in the SubmitOnLoad method, the hidden values are no longer available in the request object.As a result, the page gets into an endless loop.

Any ideas?
