This has been mentioned a few times on this list and seems to be related to GAE 1.7.2+. Prior GAE versions don't seem to have this problem. Also, I seem to recall that the bug only occurs on the development GAE server and not in production.
This seems to be caused by this issue: http://code.google.com/p/googleappengine/issues/detail?id=8201 http://tapestry.1045711.n5.nabble.com/java-lang-IllegalStateException-Sanity-check-neither-a-stream-response-nor-a-redirect-response-was-g-td5717915.html http://tapestry.1045711.n5.nabble.com/Tapestry-Problem-on-Google-App-Engine-in-Development-td5716763.html -- View this message in context: http://tapestry.1045711.n5.nabble.com/handleRequestException-tp5719921p5719926.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
