Hi Andreas,
you've spotted two things.
1). the process fails silently, that's bad, you had to use trace_flow
to detect the root error. I have to to fix that.
2). the root issue, the array is set in the process definition, using
Ruby, IIRC, the array is turned into a String, I have to check why
it's like that for now. It guess it would follow the "principle of
least surprise" if it simply worked the way you coded it.
I have to investigate those two issues.
For now, I recommend that you set such array/hash values inside of
participants or when preparing the launch items, not in the process
definition.
Thanks and best regards,
