I use js-1.5R4.1.jar inside HtmlUnit.
I get error message "The undefined value has no properties." parsing the 
javascriptt in the following HTML page:
<html>

<head>
<script language='JavaScript'>
//<!--
function buggy(){
  var option1 = document.f1.elements['select'][0];
  option1.value = 'XXX';    // This line causes the exception
  option1.selected = true;  // This line also causes the exception
}
//-->
</script>
</head>

<body onload='buggy();'>
<form name='f1' action='xxx.html'>
  <SELECT name='select'>
    <OPTION value='A'>111</OPTION>
    <OPTION value='B'>222</OPTION>
  </SELECT>
</form>
</body>

</html>

Following is the stack trace:

This is not a Rhino bug, it is a problem with DOM implementation for JS in
HtmlUnit. I guess they did not implemented indexed properties for a select
element so document.f1.elements['select'][0] returns undefined. Try to use 
document.f1.elements['select'].item(0) 
as they may support DOM item method.
