I'm not an Airbus man. But as far as understood from that incident, the cause was an "software feature" in the airbus that limits the trow of the ailerons after touchdown.
Unfortunately they had a gust and touched down with the downwind main gear, where after it was impossible to bring the wing down with the limited trow.
I believe Airbus reprogrammed the software after that incident. Correct me if I am wrong.
