Any idea why we don't fetch the ids instead of pass a resource around?
/me is confused ???
No idea ... probably just a refactor artifact.
Okay, I had the idea of go back and look who did it... apparently it has been there since the conversion from cvs to svn (talking about the previous era. LOL).
Well, I guess we can get rid of it and refactor some stuff the way it should be. O:-)
