You have to be more clear on your problem.
As of now i think this might help you,
1. Maintain a object list in session scope, add all your relevant data in method annotated as @Create.
2. On click of a link call a method and reset the values of list.
I assume that your list is updated from another page, by another user. In that case you should look at the push-functionality of richfaces. It helpd you to create a
auto-refresh, without re-loading your page. The provided examples is very clear, but you need some additional work at the
Seam-side. Read the chapters on the unwrap and factory annotations (or get the Seam in Action book) You basically need a bean which manages the user list and sends an event when the list is changed. Send an EVENT after change and let the
ajax refresh beanlisten to it.
That's basically all thre is. Don't hesitate to ask for help, but please read carefully the excellent documentation and use the examples of the distro before asking more.
