runtime service does not return running process

HelloI have a process which in certain cases does not require any userTask. In one of the serviceTasks I'm accessing the Activiy RuntimeService to receive all the running processes. for (ProcessInstance processInstance : runtimeService.createProcessInstanceQuery().list()) { System.out.println("RUN

Hi,

When you've started the process instance with the runtime service and received a ProcessInstance back the instance is written to the database.
So at that point you should also be able to retrieve the running instance with the process instance query capabilities.
If this is not working, please include the process XML and the Java code you are using.

Best regards,

Hey trademak

Thanks for your quick reply!

Yes the following code does list the running process.


ProcessInstance instance = runtimeService.startProcessInstanceByKey(processKey, variables);
for (ProcessInstance in : runtimeService.createProcessInstanceQuery().list()) {
 System.out.println("RUNNING>: " + in.getId() + " " + in.getProcessDefinitionId());
}

The problem I have is that my serviceTask is executed before startProcessInstanceByKey() returns the ProcessInstance, hence nothing is listed.
Maybe there is a way to force activity to write?

Hi,

Okay right. In Activiti 5.8 we'll introduce asynchronous continuations to solve this.
For now you can add a receive task before the service task and signal the process instance.
The receive task will make sure the process instance is persisted.

Best regards,

Thanks a lot! Got it to work with the "receive task".

Is the release date known for 5.8? Could not find it on the website.
