Sorry but didn't quite understand
Map them how ? it's not enought to do manager.completeWorkItem(workItem.getId(), resultMap);?
If not why pass the resultMap? What happens?
what method can I use in what object to get them?
The documentation simply says
"Result Mapping: Allows you to map a result (returned once a work item has been executed) to a variable of the process. This allows you to use results in the remainder of the process."
But no example is given or exaplanation to how.
