[jBPM Development] - Re: Multiple instances with synchronization

by fabiomsouto

My use case applies the concept of atomic document reviewing. A group of people gets assigned to a reviewing task of a document. The next task can only be done when all people have reviewed the code. The problem is that according to the document type, the peoples that might be interested in reviewing it may vary. That is only known at runtime, meaning that we don't know a priori how many review instances we are going to get. At the end, all instances must end, so the next task can proceed (e.g. giving a verdict).

[jBPM Development] - Re: Close issue JBPM-2537

by jbarrez

Afaik, the issue hasn't been fixed yet: the other one is closed due to duplication. We tried to fix it quickly before wrapping up the release, but it didn't work ... so my guess is it will be fixed in 4.3 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263125#4263125 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4263125

[jBPM Development] - Re: Multiple instances with synchronization

by jbarrez

As stated on the workflow patterns website: anonymous wrote : jBPM does not support this pattern. There is a proposed implementation in Java of a node-type Node to capture this semantics. As the solution relies on java-coding we consider it outside the capabilities of the proposed jPDL language So basically it means you can do it with jBPM, but it requires some Java coding. Can you perhaps explain your use case?

[jBPM Development] - Re: Multiple instances with synchronization

by fabiomsouto

I found a paper which explains how to implement some patterns which aren't provided with jBPM. Unfortunately the implementations are only for v3... jPDL 3 had a task-node, which allowed spanning of multiple instances with custom java and then waiting for all of them to complete. The code is at http://www.computer.org/portal/web/csdl/doi/10.1109/PACIIA.2008.377 , on the PDF. Unfortunately jPDL 4 does not suppor the task-node .

According to this site jBPM 3.x supports the variant without synchronization: http://www.workflowpatterns.com/patterns/control/multiple_instance/wcp12.php Is this also the case for jBPM 4.x? If yes this would be the point to start, no? http://www.workflowpatterns.com/patterns/control/index.php Workflow Patterns lists 3 variants of your desired pattern. Take a look at the patterns 13, 14 and 15. Before you can think of an implementation first of all you would have to be sure about what you are trying to achieve. Basically instead of a task or subprocess being created directly a kind of "controller" would need to be created who creates the number of process or task instances which is needed. It would need to hold a list of all created instances. As soon as an instance has finished the controller would need to be notified. As soon as it has received notifications from all instances in the maintained list the process flow could continue.

>From my point of view, this feature is extremely important. What seems the hardest is the synchronization between instances, which I cannot conceive of how to solve. If it weren't for it, it would be really easy though.

by sebastian.s

Could anybody close this issue? It's a duplicate of JBPM-2559 which has been fixed in jBPM 4.2 and which was closed. https://jira.jboss.org/jira/browse/JBPM-2537 Thank you.

[jBPM Development] - Listing outgoing transititions

by nilspreusker

Hi all, please have a look at the following thread in the jBPM User forum: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=162970 I think it would make sense to move this discussion to the development forum.

[jBPM Development] - Re: interested in contributing ?

by vchira

thx for the links. i still don't know the way this should work..i will try to bild it and make some changes but i don't know whom should i send the changes. I don't see a lot of interest in geting new developers for the project. that is why i asked if you gotta work for jboss to get the commit rights. as i know the anonymous SVN isn not realy up to date with the source code... is it so?
