I'm still having an issue with this. Is there a quick fix or workaround? Or any idea where I should insert a hack? Summary: You log into your app and an ASO is created for you You land on a page that has a form You wait until your session times out (automatically) You click the form submit. Your app redirects you to a login page, to get your ASO On success the app redirects you to your form submit request, which is a form.OnAction Tapestry gives you a NPE when trying to decode a null gzip'd stream
