Aladar and Salamon

Is it possible that the entry for Salamon 1226 in a data entry mistake?

The hungarian document lists "Aladar (szlavon)" which i take it to mean that at the time Aladar was Ban of Slavonia only, not Crt/Dal.
szlavon is very close to salamon if you are typing fast...

The closest profile match i can find is a Hungarian prince Salamon, but he died in c1210.
