Hello,
I have an unsupported item throwing the following error:
Cannot evaluate expression: "Cannot evaluate function "change()": cannot get values from value cache.".
This is the expression:
change(cfwHardwareStatusDetail.7)
where the item key (cfwHardwareStatusDetail.7) is a string containing this text: "Secondary unit (this device)"
This item is used to monitor failover in firewalls: it is working with all my assets except One.
May you help me getting some clues?
Thanks a lot in advance,
SDL
