[rules-users] Strange intermittent problem with Drools Flow

[Mauricio Salatino]

Hi Dan,
That's strange, it could be related to a non updated version of the fluent
API.
Send us the logs with warn verbosity and we will definitely take a look on
it.
If the workflow don't continue after a work item completion could be related
with some kind of threading problem.
What kind of work item are you implementing? Can you share some test with us
that shows the desired behavior?
Greetings.
