I don't think that's what's happening in my case - I'm just doing a redirect to the home page. If you have Grails 2.2.0 installed, you can see it in action in this little demo Grails app:
https://dl.dropbox.com/u/482435/shirotest220.zip 1. Go to /auth/login. Log in as 'test'/'test. 2. Go to /auth/signOut. You will see the stack trace. signOut in AuthController will show you the code. It's nothing at all special - it really just seems that there's some clash with native sessions with session handling in Grails 2 (and seemingly Vaadin as well). -- View this message in context: http://shiro-user.582556.n2.nabble.com/What-might-cause-an-UnknownSessionException-tp7578179p7578193.html Sent from the Shiro User mailing list archive at Nabble.com.
