Hmmm, yes. Great comments. Now that you mention it, I had observed this before 
but it didn't really 'click' until now. Thanks.

That's crazy, really. 
The same function hook_view() would be passed either a fully loaded node in 
case of a normal node view OR a half backed, FAPI-ish node in case of a node 
preview (either when creating a new node or editing an existing one).

I think I am starting to get this... ! ;)

Is this design flaw still applicable in Drupal 7?
Is there an issue about it?


In conclusion, if I understand well the replies I got, the problems I have 
been experiencing are to be expected and I should take care myself to handle 
special cases accordingly. 

Thanks again to all three for your replies.

Blessings,

Augustin.
