event.setCancelled(true); not working

Hi.
Bukkit 531 and 559 i try they both. and cant understand why, but anjosecurity and other plugins(including my) where using event.setCancelled(true); is not working(without errors).

i was tryed:

Code:

@Override
    public void onPlayerMove(PlayerMoveEvent event) {
        System.out.println("test");
        event.setCancelled(true);

    }

in console i see test but event not cancel

the same with onBlockPlace onBlockBreak and maybe other... and i cant remeber when it happens...

 

Didn't you forgot to register the event in OnEnable ?

EDIT: I forgot, OnMove doesn't work like that, I think its a lag problem, you need to do a hackish solution... teleport the player back to the original place

 

thank you. player.teleport works for me.
