Re: Extending 'emacs-lisp-mode' Disables 'auto-complete' for It

If I open some *.el file, I automatically enter my elisp-mode as shown 
in my first mail. But as I said auto-completion does not work even 
though the hook should turn it on. However, I've just tried your 
suggestion, i.e. after opening some *.el file, I type:

[M-x] auto-complete-mode

then auto-completion starts to work. Why is that? I mean in the 
configurations I already have:

(global-auto-complete-mode t)

Why should I turn on auto-completion manually like that for my 
elisp-mode, but I don't have to do anything for the standard 
emacs-lisp-mode?

Thanks,
