@Adrian, jBPM does not (imo) avoid assignment states at least not at the technical level. The technical level being jbpm, the businesslevel the processdefinition. Some explanation: You can see if a task is assigned to a person or a group. You can see if it is started, suspended, resumed and ended. Declining a task can be seen as reassigning it back to the pool (if there is one). Declining something at the businesslevel would mean taking a certain transition. Something that is logged as well. @Tom: I agree, not to many nodes, functionality where it belongs and making things pluggable (a real good idenity module being (imo) the most important one). Mail could be extended as well to support mime (so html messages can be send), but I'm not even sure jBPM should do all this. Why not leave some functionality up to other SOA parts. ESB conatains mail sender as well. Why not put services in there? But that is another discussion View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135806#...
