Pier component state when redisplay the page

Hi, i work with Pier 3.0.0 I have a pier site with a menu to manage some pages. Some of this pages are configured to manage components. For test i add some Counter seaside application instances. Now when display a specific page with some counter it work fine: i can change any specific counter instance in the page. My problem is when i change the menu for display another page. In this case when redisplay a page with the counters all instance are reset to 0. Now my question is: what do i do for redisplay the counter at the last update ? I need to configure something ? Thanks for any considerations, Dario
