How to persist process state between 2 JavaDelegates?

Dear community,I hava a simple setup with 2 JavaDelegates in sequence. If an exception is thrown in the 2nd class, the workflow stops as expected. If I start the excecution with the same business-key again, the 1st and 2nd task will be executed. So Activiti starts from beginning again. What I need i

you either have to include a (non-functional) waitstate for this e.g. with a timeout on it of 1 second, or wait for the 'async' functionality (http://jira.codehaus.org/browse/ACT-126) to be implemented.

Thanks for your answer, Roland. Do you mean by waitstate the Java receive task? (http://www.activiti.org/userguide/index.html#bpmnReceiveTask)
I don't see a way to specify a timeout there. Or are you refering to a Timer Boundary Event?

Hi,

Yes a Java receive task would do the trick. But you'll have to signal it before it completes the task.
You can add a boundary timer event to do this for you, but it clutters the process diagram a bit.
The Timer intermediate catching event is also a possibility, and probably the cleanest way to do this.

Best regards,
