Process with many nonestart events with different initiators

udoderk — Mon, 14 Jan 2013 22:14:57 GMT

Greeting activiti friends Some business process has a many none start events, that ordered to different swim lanes. In other words each none start event can be started by one and only one initiator like that "diagram":_________________________________________________________________(start event 1

You can use multiple message-start events (http://activiti.org/userguide/index.html#bpmnMessageStartEvent) on your process. Instead of just calling startProcessInstance, you'll have to use startProcessInstanceByMessage(String messageName);.

If you want to use explorer (and you don't control what API-call is done when starting a process), you're only option is to use the activiti:initiator="${initiator}" construct with a single none-start-event and a exclusive-gateway which decides based on the "initiator" variable, which path to take.

thank you in advance for your help and tip with "${initiator} variable!

I test it solution with success! I tested also the approach without gateway, only with conditional flows "Exclusive Flows without Gateways"

P.S The example of use with gateway:
