• The demo folder was added to the file system after updating the JobScheduler and JOC Cockpit to the snapshots from 31.03 16:14.
  • The demo folder is only shown in the screenshot of the Resources / Process Classes folder despite use of Ctrl F5 and restarting the Cockpit.
  • The Object Tree in the Resources / Agent Clusters view is no longer being updated.
  • The parameters for the agent_clusters POST request are only including the folder: '/test' object and neither the root nor the demo folder objects.
