Of course, the object is pushed on the stack in every case (inside the scope of the iterator /bean tag) but , apart from that, the var/id attribute is used to place it (with that name!) in the ActionContext, and it will remain there even outside the tag scope, after it has been removed from the stack.
The docs seem (to me?) to imply that the name is used for pushing it onto the stack (which doesnt make sense).
