Hi,
I use Activiti Designer to create a diagram which is consisted of 3 UserTask. But when I save it, It cann't generate BPMN 2.0 xml and give error message:"UserTask ChuangjianrenTask has no assignee, candidate users, candidate groups set". There isn't User or Group icon in Designer Palette.
Do I have to manually modify the xml of diagram? And How to add assignee, users, groups?
