[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

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

by kukeltje

wow, we have a noob here in the forum... ;-) Yes, sounds logical. But this means that signalling via the api should set this variable? or can we have an additional solution that if there is a textual (non formal) condition that when signalling flow name/id is used. I can implement anything like this, but it has to be very specific. Including things like what if there is no flow that has a condition that evaluates to true. etc...

Maybe it is a good idea for the time-being to just make it work and file a jira issue for a real solution. That way it can work for everybody by using the source, but the issue is not forgotten. And now we are into languages anyway: "als het niet kan zoals het moet, dan moet het maar zoals het kan" is what we say in Dutch. (finding a proper translation I came across: if it ain't dutch it ain't much. Something completely different, but just as true) 1 Heineken for each proper translation as google fails miserably View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246786#4246786 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4246786

[Design of JBoss jBPM] - Re: [BPMN2] use ids or names from bpmn 2 XML?

by kukeltje

Yes, I prefer Id's as wel, since they are checked against all refs when checking the xsd. sequenceflows that point to non-existent activities are automatically found. Including e.g. when you point the 'default' attribute in the exclusiveGateway to a non-existent sequenceflow.

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

by camunda

Hi. Just wanted to write it down for now: Since BPMN defines more than one outgoing flow as AND-Split (fork), this applies to the UserTask as well. This means, the XOR semantic from jPDL, where the user selects a outgoing transition, cannot be applied here. In my opinion it must be modelled as conditions on the flow (assume we have Java Expression Language): #{outcome == "ok"} #{outcome == "cancel"} Now the outcome can be set by the task management like in JPDL and it works the same. Sounds logical?

by camunda

damn it, it is final :-/ Otherwise it works, I just hacked it right away and removed the final ;-) I exchanged the execution.proceed() with fork(execution)... But maybe Tom or Jorram have some ideas how to do that correctly?

Hmm, maybe overwriting and exchangig the "ExecuteActivity" isn't the worst idea? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246751#4246751 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4246751
