As we are close to the deadline to decide if we are going to use jBPM 5 in our project I ask again for further clarification.
Maybe Mauricio (who is very active at the moment) could help?
You can ignore the topic "Human task service and transactions" (see post #5) as it is discussed here: http://community.jboss.org/thread/162963
But it would be really nice if we could expand the descussion about session scope and timers!
