[Design of JBoss jBPM] - task assignee vs owner

by tom.baeyens＠jboss.com

we could distinct bewteen the owner of a task (the one that has the responsibility) and the assignee (the one that is supposed to make the next progress for the task). distinction use case: manager gets a task and delegates to secretary to perform fill in some of the task form details. the manager wants to keep full control. the secretary is only allowed to fill in the form, but not submit the task. when the secretary is done, he/she reassigns the task back to the manager. is this usefull ? did you miss this feature in jbpm 3 ? it does introduce some complexity in the sense that in the api, we have to distinct between owner and assignee in the assignment related interfaces.

[Design of JBoss jBPM] - process definition as a resource

by tom.baeyens＠jboss.com

jbpm users typically deploy the process to the db and then store the instances in the DB as well. we also supported non persisted execution of processes to some extend. after thinking this through, there are basically 6 execution modes. see next comment in this thread for a reference to the presentation on execution modes. 2 of those 6 modes are now in the test suite: dynamic persistent and memory but i want to discuss persistent resource. In that execution mode, the process definition is loaded from a resource on the classpath. the process executions still live in the DB and the history can also be captured in the DB. in order to achieve this execution mode, we must change the references from the execution datamodel to the process definition datamodel. the references cannot be based on foreign keys, but they must be based on just the plain activity name. in a lot of situations, i think this would be the most appropriate/optimal way to deploy and run processes. some questions: in the persistent dynamic execution mode, do we want to keep using the foreign key mappings ? or would it be possible to transition to text-based activityName references as well ? in the latter case, we would be able to keep the same hibernate mapping files for both execution modes. if we can find a good solution for text-based activityName references then targetting the 'persistent process resource' execution mode becomes a possible target. outside of the current activity pointer, there are a number other of foreign key references in the execution datamodel. we would have to do all of those text based. another aspect that becomes more complicated in 'persistent process resource' execution mode is deployment in a clustered environment. when using the DB to store process definitions, this is the single entry point accessible from all nodes. but how would we deploy a resource to all nodes in a cluster ? and how would the process definitions be cached in memory ? ok... my thoughts are not yet clear and structured. but i wanted to start this discussion. cause if we want to include the persistent process resource mode for GA, then we need to discuss now and start working on it in the next iteration.

[Design of JBoss jBPM] - update: working on task management

by tom.baeyens＠jboss.com

last week i did an initial take at the business intelligence information. this week, i'm going to start by merging task module in the pvm. and try to build out the full model behind task mgmt. koen, i don't know yet to what extend i'll also have updates to the jpdl language. i'll sync with you as soon as that becomes clear.

I agree, there are a lot of people who ask me the same question... It's not mandatory, but it is a nice to have I think.

Okay, now I got it. This is indeed a very good improvement! I will try to have a look at the code asap (but cannot yet promise that I will have time :-/)...

[Design of JBoss jBPM] - Declaration of process variables in jpdl 4?

by camunda

Hey guys, I just had a recent discussion and remembered how often I (or the forum) was asked if it is possible to declare variables for a jbpm process (via XSD or Java types). This would be interessting if it will be supported in jbpm 4. Not mandatory but possible, since a lot of people want to declare there process variables, and it is an understandable requirement I think.
