Given that I received a lot of replies about this topic it is very difficult
for me to thank all the people one by one, so I want to thank you
all together in this mail :-)
Thanks again and sorry if I haven't had time to thank you directly.

Oggetto: Re: How can I show some results at a time?
Checkout the TableView component from TICL (http://www.kobrix.com). It's got
automatic paging and a search engine-like pager as well.
There's an example on the site under the menu TICL->Examples of the
tableview stuff.
When I use it, I do the query to the DB on every request, but I'm sure you
can store the results in the session and pass to the tableview as well.
