    ****************************************************************
    When a task is launched, a user group name for task
    collaboration/notification is automatically generated by
    Process Portal; for certain languages, the group name is
    encoded into a base64 string, which can contain slash ('/')
    characters.  The Process Portal code then creates a
    "channel ID" based on the group name (channel used for
    notifications, in conjunction with the Process Portal
    notification application), and then builds a URL based on that
    channel ID.  If the group name starts with a ('/')
    character, the resulting URL would contain a double slash
    ("//") sequence, and this an invalid URL.
    

Problem conclusion

  • The Process Portal code was modified to encode '/' characters
    in group names during notification channel ID/URL creation to
    ensure that double slash sequences do not occur, resolving the
    issue.
