Also I forgot to mention that the Dropdown control is what you should use in new development, and there is an example in the UI Gallery of some working dropdowns. You can view the UI Gallery with Designer Studio > User Interface > UI Gallery , and will find Dropdown in the Available Components area of the UI Gallery landing page.
- Routing identifies who will work on an assignment as a case moves through a life cycle. Assignments can be routed to worklist or workbasket:
a) A worklistis a list of all open assignments for specific users. A user see an assignment on their worklist until the user performs an action that completes the assignment. Each user has a worklist that the user can access from user portals.
b) When assignments are queued for a team of users, the assignments are stored in workbaskets. A team associated with a workbasket is called a work group. Assignments stay in the workbasket until a team member selects an assignment or a manager sends an assignment to a specific user. A user selects an assignment from the workbasket and begins work.
- When you add an assignment to your process, you specify the assignment's router. A router is a special type of activity that uses a routing destination and an assignment type to advance an assignment. The activities use parameters to control routing behavior. Routers can use user roles to control routing behavior or use user skills to direct assignments. Also, use the results of a process decision rule to route assignments. The ToDecisionTable router uses the results of a decision table to route an assignment.
