Hi Marton. Yes, you need to explicitly call setAttribute() when you modify
any object in the session. Otherwise, the object won't be updated in App
Engine's cache/datastore, which are the mechanisms it uses to back sessions

Have you enabled session ? By default it is read-only.

App Engine includes an implementation of sessions, using the servlet
