The behavior I want on some activities is that multiple, say, five people, get assigned the work list item, but when any one of them completes it, it disappears from all of them.
I thought I could accomplish this by simply having a role that the activity is pointed to, then putting multiple people in the role. This doesn't seem to work... all of them get the email saying "worklist item received," but only the first one on the list gets a worklist item... and if anyone else clicks the link in their email, they get a "No actions available for this user" web page.
Help?
