Problem summary

  • Problem Description:
    When defining task assignment (aka task routing) in terms of a
    custom user list, the sequence of claiming the
    task and assigning it back to the initial custom user list will
    result in the task not being assigned to
    any user or role, thus rendering the task not operable.
    
    Problem Summary:
    Custom user lists are internally mapped onto ad-hoc groups. In
    order to keep the number of ad-hoc group low, such
    groups are deleted internally after claiming a task. Such
    deletion concerns DB entries, but not the
    group entries maintained in a memory cache. When reassigning the
    task back to the initial custom user list, the
    initial ad-hoc group is found in the memory cache, but has no
    entry in the database.
    
    Problem Conclusion:
    The deletion of the ad-hoc group is removed, so that cach and
    database entries fr the ad-hoc group never get out of sync.
    Removal of unnecessary ad-hoc groups is covered by a separate
    mechanism.
