Sorry didn't check the website, I am not getting the emails to my inbox, will
try to subscribe again. I will get back to you with the exception I was
getting if you don't set the valueStack to null.
Thanks, Prasanth

Thank you very much for your time and report!
[show/hide original text]
Hmm... so how and why `request.setAttribute("struts.valueStack", null)`
works.
That's weird and so very important to me :)
Could you please see what is the type of request when you receive it in
your second context filter? e.g. println(request.getType()) before those
your two lines (I could see myself but maybe it will be different from
your one!)
Thanks in advance!
