This is a good point, and I have discussed this at length with my colleagues.  But, if you think of nested conversations as continuations (http://www.brainbell.com/tutorials/java/Continuation_Servers.htm),  the implementation of the Seam conversation model suddenly makes perfect sense.  I actually posted the breadcrumb issue you raise as a topic:


Actually, simply filtering the ConversationStack by view-id yields the expected results from breadcrumbs with the continuation view of nested conversations.  I can post the filtering code if you or anyone is interested.  It is simply a component that wraps the ConversationStack.

I will soon be posting an extended seam-booking example with an accompanying article that will illustrate the continuation approach in-depth.
