Hi Matt,
you can do
wfid = fei.wfid
wfid = fei.workflow_instance_id
It's explained at http://openwferu.rubyforge.org/padmin.html (in the
first code block IIRC).
A process instance is made up of expression instances. Process
instances are identified with a "workflow instance id" (wfid),
expression instances are identified with a "flow expression id" (fei).
As expressions belong to processes, fei instances do contain the wfid.
get_process_status and get_process_stack should accept fei as a param
directly, as a convenience, but usually you can write :
s = engine.get_process_status fei.wfid
Hope this helps, best regards,
