Hi all,
I have a process definition catching a signal at an intermediate event and throwing the same signal at the end event of the same process definition as shown in this cawemo example
My problem is, I start a first process instance, this process instance take an arbitrary time to execute because of “some task”. A second process instance is started and waiting at “wait current execution ended”.
When the first process instance is ended, the second one is never notified, therefore, when I GET /engine-rest/event-subscription
I’m able to see the signal subscription and when I POST /engine-rest/signal?name=XXX
camunda is throwing a NullPointerException
:
org.camunda.bpm.engine.rest.exception : ENGINE-REST-HTTP500 java.lang.NullPointerException
at org.camunda.bpm.engine.rest.impl.SignalRestServiceImpl.throwSignal(SignalRestServiceImpl.java:41)
After a little inspection it seems that SignalDto is null and I don’t understand why…
Thanks in advance for your help.
Anthony
