I am trying to implement task sharing feature for a particular user. I have two users (User1, User2)
User1 has some task in his to-do list. User1 wants to share it with User2. I have changed the preference setting and allow the User1 to share his task to User2.
Now User2 can see the User1 queue left to the To-do list but it is empty.
I have tried to run another process instance and it is comming to the User1 to-do list but it is not appearing in the User2.
Do i have to do some extra configuration other than of workspace preference setting?
What you have tried is task delegation; which means this task can be done by only one person.
If you need to share a task, use the Gateway modelling elements to assign task to parallel users (in your case user1 & user2).
This should be done through your process design in workbench ES.
"If you need to share a task, use the Gateway modelling elements to assign task to parallel users (in your case user1 & user2)."
The Gateway won't allow you to share a task. You'll end up with two separate tasks assign to two different users in parallel. If you want to share the same task you need to share you queue from the Workspace preference so that another users can see your tasks.
There is a "Use ACL on shared queue" option (or something like that) on the user step that you might want to play with that might help.
I can't test right now, but I think that might be the problem.
