Ok, in fact I want all the objects from the list, but not in the same table,
that's why I dont think a Loop is usuable, because I won't display them one
after the other.
But even if I provide a getter for my object, I don't think I can tell my
page which object for the List to render (because it changes).
Now, I have instanciated all the 15 Objects of the list, and I provide 15
getters... But I don't think it's very optimal !!
Thanks a lot for your help Chris !!
