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.

Hi,
I recently run into some problems when trying to create a simple holiday
request process.
I defined process variables but I struggle to understand how to access them
in Human Task.
In my User Task ,,holiday approval" I have this as a description:
#{employee} requested holiday for #{length} days
I set both variables when I start the process and the result looks as
expected, for example ,,John requested holiday fo 14 days.
But lets say I want a manager approving the holiday request to add his
response as a variable. How do I do that?
I tried to use the Result mapping with someting like this:
response=response but I get an error saying ,,There is no ID/IDREF binding
for IDREF '_2_response'.
Also if I manage to get this running, how do I set this variable in a
client app?[using WS_HT]
I am sorry if I am asking realy basic things, but I realy need some advice.
Bellow is the process definition.
Thanks a lot, matus
