Multiple Instances without a priori Run-Time Knowledge

[house0128]

hello,I have a question.Does Activiti supports Multiple Instances without a priori Run-Time Knowledge? http://www.workflowpatterns.com/patterns/control/multiple_instance/wcp15.php

[jbarrez]

No not yet. But since it is part of the BPMN 2.0 spec, it will be implemented at some point in time.

Sorry to open a long dead topic, but I was wondering if any progress has been made on this subject.

Thanks.

We support multi-instance, read about this here: http://activiti.org/userguide/index.html#bpmnMultiInstance

The "without a priori Run-Time Knowledge" can be sort of accomplished by using the completion-condition on the multi-instance, to determine another instance should be created.

Cool, I'll give that a shot.  Thanks!

Wir möchten das Workflow Pattern WCP-15 (http://www.workflowpatterns.com/patterns/control/multiple_instance/wcp15.php) mit Activiti Version 5 implementieren. Dies ist aber nicht direkt unterstützt. Ist es möglich, das zu modellieren oder müssen wir das programmatisch lösen? Habt ihr schon Erfahrung mit der Realisierung bzw. Automatisierung dieses Workflow Patterns?

Danke für ihre Antwort

Hi San,

From my point of view "Multiple Instances without a priori Run-Time Knowledge" pattern can be supported in two ways:

• extending the engine to support it (java implementation)
• I think the implementation is feasible with activiti 5 BPMN20 support too. (based on the events we can run several independent instances and synchronize them at the end)

Regards
Martin
