If the DB variable Persist.WellKnownProxyClass names a deleted but loaded config item in Value List Object, the system posts an error.


The configuration file does not load, and the system posts an error similar to the following: Error 0x1020036 occurred: 01020036:3: The requested value_list (/Common/test_group) was not found.


This occurs when the configuration item was removed from the running config, but exists inside a saved config.


Load the UCS file a second time.

Fix Information

Persist.WellKnownProxyClass referencing missing object no longer fails with object-not-found error.
