* * * New or Improved for 2013.2 * * *  Task-Incident Workflow

Before you can close an incident, all of its tasks must be closed. Also, once all tasks within an incident are closed, the incident status should automatically change to resolved, or a new task automatically created. However, you can close an incident regardless of the status of its tasks. This automatically closes any open tasks within the incident.

You cannot update incidents when they are in the logged status.
