HI,
I've noticed (on my colleague's computer running Activiti Designer in Eclipse Kepler, on Windows 7) that it is possible to open a diagram for subprocess by using "Open process <subprocess id> in new diagram" option which exist in Call Activity's drop down menu. The problem is that this option does not exist in Activiti Designer in Indigo, Juno or Kepler on Windows 8 on my computer.
Have somebody else had similar experience, or made this option visible after it hasn't been?
