[Design of JBoss jBPM] - Re: [BPMN2] Task-Outcome must be implemented differntly

I will just set a variable "outcome" in the UserTaskActivity.signal method with the value of the signalName? BPMN spec doesn't say anything about it (or I missed it). I think this is a good solution at least for the moment, what do you think? Tom wrote : | But we can also consider adding a BpmnService which allows the user to enter "BPMN" messages that the engine has to react to.

If we want to leverage full BPMN vocabulary we still can write that facade...

Generally speaking refactoring is always about functional and passing tests.

I'd call it "experiment" or "prove of concept research" with high probability to fail at the end :( View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246882#4246882 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4246882

by tom.baeyens＠jboss.com

i'm not sure if i get the point exactly. in any case, the parallelism and condition evaluation should go in the leaveBpmnActivity. so that by default, each outgoing transition is evaluated and forked if the condition resolves to true. another aspect is that we should consider extra services. executionService.signalExecutionById might be fine. But we can also consider adding a BpmnService which allows the user to enter "BPMN" messages that the engine has to react to. This way we can offer the real BPMN terminology to the BPMN users. On the other hand, leveraging the ExecutionService might be easier to get started in the beginning.

[Design of JBoss jBPM] - Re: [BPMN2] How to implement uncontrolled sequence flow beha

by tom.baeyens＠jboss.com

btw, if bpmn would have had the synchronizing default, it is not more difficult then the parallel outgoing default. it's all a matter of methods in the base activity classes. during pvm research i experimented with extra support for these concepts. (synchronizers and propagators) turns out that all the convenience support that is build in for one use case is inconvenience for another use case. eventually it all boils down to implementating the runtime behaviour of an activity. so pvm should only have one method to implement that behaviour.

[Design of JBoss jBPM] - Re: Re-using the REST facade

by jbarrez

Ah now I see your problem. That's indeed a tricky one to solve without hacking (a lot) the jbpm-console integration code. Your suggestion to push your own process engine to jndi doesn't seem so unreasonable, but I'm wondering how this easiliy could be done, since the processengine is only accessible on the JBoss server.

[Design of JBoss jBPM] - Re: [BPMN2] How to implement uncontrolled sequence flow beha

by tom.baeyens＠jboss.com

the real solution is to implement it in the BPMN activity base class. add a method to the BpmnActivity like leaveBpmnActivity(ExecutionImpl execution) changing the pvm in this respect is not desirable. the generic behaviour of the proceed is something that i think over time should be faded out. activities should be explicit in what they want to see happening. combined default behaviour like in the proceed is always process language specific. so it doesn't belong in the pvm proceed. it belongs in the process language specific base classes. (ps you already might have noticed that in our own implementations, it is best to use the impl classes and not the interfaces) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246857#4246857 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4246857
