Well I tried all approaches but I had a small problem with the javascript
redirect approach: I perform an AJAX operation and my interceptor redirects
to a page which displays the error message and has an inline javascript to
redirect to the login page as suggested.
It works fine in firefox but in IE I simply get "undefined" in my div area.
I tried out something simple and had a result page with this javascript:
<script type="text/javascript">
<!--
window.location.href = "/newbie/login.action";
//-->
</script>
Unfortunately it doesn't work. Any suggestions?
