Ender Dragon does not obey NoAI tag

I have this issue as well. He still moves and destroys blocks.

They said, that this function works on about 50% of mobs.

Can confirm still in 14w34d.

Confirmed for 1.8pre1

Are they going to add it for all mobs?

Confirmed for 1.8. According to MC-68988 CustomName does not work either.

Confirmed fixed. (Though now it is unable to be damaged and doesn't flap its wings but that's a minor issue)

Mmm, okay, so I created one in 1.8.1-pre2 on a 1.8 vanilla server.
The enderdragon is floating.
But an invisible enderdragon is destroying everything.

Mmm, okay, so I created one in 1.8.1-pre2 on a 1.8 vanilla server.

This is probably because the client (1.8.1-pre2) thinks the Enderdragon is NoAI, however the server (1.8 where the bug hadn't been fixed) thinks that it flies around and destroys blocks like normal.

this is kind of fixed, but NoAI dragons cannot be teleported with commands, nor can they take damage, even with /kill
