Of course, nothing prevents one writing a semi-automatic workspace
management layer on top of Seam that would take care of detecting and
closing abandoned conversations (for example, along the lines I suggested on
the Trails list). The Seam guys have carefully removed any dependencies to
JSF. In practice, integrating Tap5 with Seam might be the fastest way of
getting practical results for a conversational scope, and wouldn't solve
only one but two problems at the same time (conversations and
session-per-conversation), of course at the expense of tying the
implementation more closely with Hibernate or at least JPA, but that's
probably what the majority is using anyway. I'm sure the Seam guys would
love to see Tapestry support for Seam. And btw, Wicket guys have already
done this. Given that you Geoff are probably inclined to use J2EE container
anyway, wouldn't it make sense to you to start looking at creating
tapestry-seam integration project? It might be an interesting project to
take on for me as well.
