Tried multi-instantiator with 5.2 works fine.. Please see the usecase and the attached bar.. As usual what i have provided is only a simple example and obviously can be improved further. But i leave that to you ;-)
My Usecase is that.. When you start the Main process with a list of usernames (comma seperated) for example (john, jack, james)
Multi-instantiator has to create respective number of subprocess and create task and assign to users respectively. (from example above three tasks one to john, jack and james respectively)
Upon completion of all subprocess tasks the main process should complete.
Try the same by deploying the bars from userexperience.
