/confdConfig/cli/jShowUnset (boolean) [false]
jShowUnset is either "true" or "false". If set to "true" then the J-style CLI will show unset leaves with
the value of jShowUnsetText when doing "show configuration".
/confdConfig/cli/jShowUnsetText (string) [UNSET]
jShowUnsetText is the text printed for unset values if jShowUnset has been set to true.
Why I can not display "UNSET", even if i set "true" to the node "/confdConfig/cli/jShowUnset" ?
