I don't have an example here.. but as far as I remember you define the swimlanes at process definition level and after that you can use an expression to set the property assignee to that swimlane.
In the BPMN file you should be able to see something like
the scenario i want to do is the following:
there are 3 users
krisv, mary and john
krisv and mary belongs to one swimlane
and john belongs to another
the process exists out of two tasks,
one task sits in the swimlane where either krisv or mary can process the task
and the other task in the swimlane where only john can process it
is it possible to configure it this way ?
that's the idea!
do you maybe have an example?
I can work on one.. but that will take time..
