JSF & Seam vs Tapestry & HiveMind

[Andrew Pym <an...@optimalexecution.biz>]

Am I right in that JBoss has come up with a product which is very HiveMind like in Seam?
http://docs.jboss.com/seam/reference/en/html/pr01.html

The documentation puts Seam at the Context Management layer,
Above EJB & Hibernate but below JSF and Presentation layers,
although also described as a uniform component model which hooks into jBPM

Am I right in saying that HiveMind does context Management plus a bit more and has a bit more flexibility than Seam?

Does anyone have any suggestions for hooking Hivemind & Tapestry up to a workflow engine eg OSWorkflow or jBPM?



Regards

Andrew

I think probably Hivemind/Tapestry can do it if we strengthen its 
session model. For example, including "conversation-scoped" ASOs, 
another way of building ASOs rather than the StateObjectFactory, etc.

AFAIK Seam's mission is to "fill the gap" between the EJB3 container 
persistence layer and the JSF presentation layer.
The idea is that both EJB's entities and JSF's model objects are beans, 
so why should one want to write session-beans to link those objects.
Seam should be this "linker" that ties up the JSF View directly with 
persistent beans. It also introduces new conversation scopes for the 
lifecylce of those beans.

So my opinion here is that trying to use Seam without JSF could be done 
but it would be kind of twisting the original idea behind the framework.
Maybe Spring Webflow could be a better choice?
