Hi guys,
I am working on the same case and I also have a problem with the signal event. Maciej's answer helped me, I can call the signal with the url:
/rs/process/tokens/[processInstanceId]/transition?signal=[your-signal]
and the signal is transmitted to the process. But when I add ^[event-object] at the end of the url, it raises java.net.URISyntaxException: Illegal character in query . I think the ^ doesn't work in the url.
How did you manage to pass a parameter with this event-object?
