Hi Edward, See if this posting might help: http://www.objectstyle.org/cayenne/lists/cayenne-user/2006/04/0073.html In a nutshell, when using Tapestry 4 + Cayenne, I don't serialize any Cayenne objects through Tapestry. The posting has more details. /dev/mrg PS. I used to pass my objects around with an ActionLink (now deprecated) in Tapestry 3, but changed my techniques when I moved to Tapestry 4. Also, I only use DirectLink now -- PageLink has some session quirks.
