It is really necessary to use a persistent store when all needed data is
transmitted with each submit of the form?

Tapestry does redirect-after-post by default, so some form of persistence is needed. You can also use the activation context to pass this information back to the page whithout usin @Persist or @SessionState.

You can disable redirect-after-post (documentation at http://tapestry.apache.org/tapestry5.1/guide/conf.html), but I don't recommend this option.
