In Jbpm (I use 6.4), there are process variables that I can use in my tasks. For example, I have the process variable "groupId", in Eclipse BPMN Modeler, for my Human Tasks, I set its value in the "On Entry Script" section and provide it in the Group Id section, so I can dynamically define the actors of a human task.
My question is if I can use some kind of a narrower scoped variable (task scoped or node scoped) for this, since my concern is that in my process, I have a parallel gateway and three human tasks are executed "in parallel", therefore they can't use the same process variable "groupId" (or can they)?
