I realise you are referring to more than just Conversations support but
I'll just address Conversations since I don't know what other benefits
you're hoping to get.
>From my reading, Wicket's Conversation CDI module is at best controversial,
eg:
http://comments.gmane.org/gmane.comp.java.wicket.devel/29265
and the rationale for it has been questioned, eg:
http://apache-wicket.1842946.n4.nabble.com/Conversation-scope-in-wicket-td1885269.html
In any event, you can easily add client-side Conversations to Tapestry.
JumpStart has a drop-in solution that gives you these methods:
startConversation();
saveToConversation(...);
restoreFromConversation(...);
endConversation();
You just drop the Conversations and Conversation class from either of these
examples into your project:
http://jumpstart.doublenegative.com.au/jumpstart/examples/wizard/usingformfragments/START/wiz4
http://jumpstart.doublenegative.com.au/jumpstart/examples/wizard/usingpages1/wiz5
It saves the conversation in the session, but you could easily re-implement
it to use the database if that's your requirement.
If your requirement is server-side Conversations then don't forget JEE has
an existing solution: stateful session beans.
