Hi Ronald, Maybe I did not explain my self correctly, sorry. I don't understand very well what you say, but now I'm invoking the startProcess and it returns immediately and my process stays on a waiting state. What I need is to call the executionService.startProcessInstanceByKey(...) and wait for the process end, without active waiting. I mean, the caller calls the startProcess* and waits for its end. The process is complex and has multiple human tasks. In addition, is there any callback that can be used to communicate the process end to the caller?
