Hi Toby, from http://tapestry.apache.org/tapestry5/guide/appstate.html
"The default persistence strategy, "session", stores the ASOs inside the session. The session is created as needed." "Generally, you will configure an ASO if you need to change it from the default persistence strategy. Right now there's only one built in strategy, but more will be coming in the future." But, as any java app, you can do this with static object. Marcus Veloso
