3:31 a.m.
That exactly what I tried, but I allways got the error about ,There is no
ID/IDREF binding for IDREF '_2_response'. or some other parameter. Is there
some required naming convention?
What I did is set In mapping like this employee = employee, length=length
response=response and the same for out mapping. Maybe my IDE produces wrnog
bpmn document. Could you post a snippet of your bpmn document?
Thanks a lot

You need to use both mappings
IN Mappings (Parameter Mapping in the IDE): this will copy your process
variables to the work item scope
and OUT Mappings (Result Mappings): this will copy the information created
or modified by the work item (in this case a human task) to the process
scope.
Greetings!
