There are two problems with this approach it seems:
1. Item is added at the very end of the list (not a big issue but
really inconsistent with the rest of the pages on the Internet).
2. If you hit the browser's Refresh button on just loaded page, you
would see your item two times.. click more - more items are added to
the data provider.
I do not yet know how to resolve #1 (I'm just a few days into a whole
JEE stuff), but for #2 it can be easily avoided by adding a property
to the SessionBean which will indicate if it is the first time page is
loaded during the session.
