KB001589 is a list of high priority issues for K2 blackpearl 4.6.7 that have been resolved.

Issues Resolved

K2 Server

  • When deleting a group from Active Directory, the group is not disabled in the database.  This causes an error stating: "Failed to resolve 'K2:{Domain}\{Group}': The specified account does not exist. Resolving User:{Domain}\{Group}" in the K2 Host Server log file.
  • If SharePoint Alerts are set up to notify a user when changes are made on a SharePoint Document library or list and the Identity Service cycled through the SharePoint Security Labels using an account that an alert was set up for, if that account is not explicitly part of a Group membership on the SharePoint site, the alert gets deleted.
  • After deleting an IPC parent process, duplicate child process records for the deleted parent process are created in the IPCAsync table.  Another issue is when a parent process is in error state, the IPCAsync table does not process child process threads.
  • When executing multiple instances of the ViewProcessInstance method, the K2Server stops processing with an error stating: "Null Object Reference".
  • Unauthenticated users are allowed to make changes to the K2 License from both K2 Workspace> Management Console> Licensing and K2 Process Portal.
