startProcessInstanceByMessage

alistair — Thu, 08 Nov 2012 16:08:41 GMT

Hi,I'm trying to utilise a model containing a none start event and a message start event, which has a different entry point into the flow.In my unit test I'm therefore utilising the startProcessInstanceByMessage method on the runtime service and using the message name as defined against the process.

How does your bpmn xml looks like regarding this start event?

Hi,

The links you posted do not work for me. But you can have a look on following test in the git repository to see how signal start event works. Following example is not exactly the same, but maybe it can help.
org.activiti.engine.test.bpmn.event.message.MessageStartEventTest#testMessageStartEventAndNoneStartEvent

https://github.com/Activiti/Activiti/blob/fd1e6259142d8050f5ab3c7d81b33e303b1b85ef/modules/activiti-engine/src/test/java/org/activiti/engine/test/bpmn/event/message/MessageStartEventTest.java

I have exactly same issue. Trying to start a process with messageStartEvent. This is how I am trigering the flow in my main method:

public static void main(String[] args)
{ repositoryService.createDeployment().addClasspathResource("diagrams/messageProcess.bpmn20.xml").deploy();
Map<String, Object> processVariables1 = new HashMap<String, Object>();
processVariables1.put("newCustomerId","Ram");
ProcessInstance processInstance = runtimeService.startProcessInstanceByMessage("newCustomerRequest", processVariables1);
}

I am getting exception: Cannot start process instance by message: no subscription to message with name 'newCustomerRequest' found

I think I got my answer.
From user Guide:
<b>Message start events are only supported on top-level processes. Message start events are not supported on embedded sub processes.</b>

My usecase is: to halt at a wait state that should get triggered from outside (without user task) and continue the flow.
Any suggestion (please elaborate simple things also, m new to activiti) would be highly appreciated and very helpful.
Also, plz tell me how to upload my workflow images (without using google site if possible) on this forum.

Thanks Martin. Had gone through the repository code. I am now able to resolve my earlier issue now.

But still i am facing issue in my new implementation. Here I am having 'message start event inside a subprocess' thats gets triggered outside by java service task using 'runtimeService.startProcessInstanceByMessage("waitMessage");'

Please help me why I am getting exception as <b>"Exception in thread "main" org.activiti.engine.ActivitiException: Cannot start process instance by message: no subscription to message with name 'waitMessage' found.". </b>

Many thanks for any help..
