Thanks. The Hivemind article was really helpful. The property injection into an ASO thing looks as though it oly happens when the ASO is created, not on every request, so I can't use it, but it was helpful knowledge, nonetheless.

There is a how-to in the Tapestry wiki which shows how to inject a property into an application state object (ASO). It does it by providing a custom StateObjectFactory which creates the ASO. http://wiki.apache.org/tapestry/InjectPropertyIntoASO If you have not seem James Carmen's article on HiveMind, you might like to check it out. http://www.theserverside.com/tt/articles/article.tss?l=HivemindBuzz Shing --- Sam Gendler <[EMAIL PROTECTED]> wrote: > I have a session state object which stores some > info, and I'd love to > put some logic in the object, too.
