Owner is wrong having learnt nothing else (2,5)

Ross

I believe the answer is:

no wiser

I'm a little stuck... Click here to teach me more about this clue!

'learnt nothing else' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'owner is wrong' is the wordplay.
'wrong' is an anagram indicator.
'owner'+'is'='owneris'
'owneris' anagrammed gives 'NO WISER'.

'having' acts as a link.

Can you help me to learn more?

(Another definition for no wiser that I've seen is " Still in ignorance".)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
