That is because there is no global $node. There is a global $user viewing
the page, but not every page has a $node that it needs to display (eg all
kinds of "listing" pages or the admin pages etc). Blocks can appear on any
page, not only node-pages. So hook_block() doesn't have direct access to a
Note that the functions that need $node always have a $node parameter
passed. There is no global $node that I'm aware of (with maybe the exception
of theming, but that is then handled by phptemplate).
the solution would be to do like in book_hook() and check on arg():

I think this is the correct way of doing this. And I don't really see how
this makes things more complicated. The test checks if we are on a
node-page, and if you are you can load the node needed. node.module makes
sure the node is loaded only once, so there is no overload either.
Isn't there a possibility to have directly access to the $node object?
Don't think so.
