I've got the same problem.
I Followed Kris' article but when double-clicking on the single process instance in the "Process Instances" view, I get an error in a pop-up "Could not find process with id com.sample.evaluation".
But when I expand the RuleFlowProcessInstance object in the "Process Instances" view, I do see the property processId="com.sample.evaluation" so I'm a bit confused.
are there any solutions for this problem?
Because lack jar.Suggestions sart your eclipse by:
then import project .it"s work OK
you can open your *.bpmn file
then change the id that eclipse rebuild
and it's work~
Thanks for the tip about changing the id of the bpmn file (and then changing it back again). It fixed the issue for me
The tip worked only with the evaluation process, with any other processes the issue remains. How to fix this?
