Ok, got the point. As I said, I have been arguing from some (dummy?)
end-user perspective. I guess other users can figure out that user
objects are normally not the same as persistent objects, too.
If I put a developer hat on, I feel an explicit "saveProperties" call
or something like that is better, too - so sorry for the noise I created.
