I will very rarely go all in or call an all in bet while holding AA. I've got to see some cards before making a tournament jeopardizing decision like that. AA is all too often beaten by lesser hands who catch their cards.
We can't really say whether you played the hand wrong or not. There are a lot of factors that go into making a judgment on something like that. How long had you played with the caller before this hand? Did you give him any reason to doubt the legitimacy of your hand? Had you shown yourself as a tight player, or shown any previous hands which might have given the caller helpful information to use against you? Was the caller a loose/aggressive player? There are a lot of things that could have made him believe he had the best hand, or he could have simply called in order to attempt the draw out. As far as making a large raise with the AA hand, I believe that was correct. However, as I said before, I hate to call an all in bet holding AA...it's a disaster waiting to happen.
