signalEventReceived() does nothing

Question asked by filajupiter on Jan 26, 2016

My process consists of an eventBasedGateway followed by 3 intermediateCatchEvent.
The signals are process instance scoped.
By calling signalEventReceived with a correct signal name and executionId (no exception raised), I'm expecting the process to continue flowing.

However, nothing happens. No changes to the db at all. No update sql is generated.
Here is the log. What could go wrong?
