I just wanted to set another calculation for the Primary User i.e. Number of logins with "Reset after 15 Days".
I get an error with:
"Error saving primary user calculation setting
See the ZENworks Control Center log file (zcc.log) for the full stack trace."


Well here it is:

] [null] [] [java.lang.NullPointerException] [ZENServer]

We're running ZCM 11.4.2.
I couldn't find anything like that, so...What causes the NullPointerException? Does anyone know that issue?
