when you just call "a" this way, it's supposed to call a default view such as 
/a/@@index.html or anything else defined as the default view. Otherwise you 
won't be able to publish "a" as is, unless it is publishable itself.

If you want to display "a" through the "b" view, but not through @@index.html 
you just have to allow the first one and disallow the second one. (or even to 
not register index.html at all)

If you have disallowed access to "a" itself but still want "b" to display it, 
you will have to removeSecurityProxy(a) in the b view.

Now, if b is not a view but an object contained in a, this is rather a matter of
