Passing Parameters to Pages (Newbie question)

Hi,

I have a question concerning the passing of parameters to a page:

Imagine two pages: ItemList and ItemDetail. ItemList basically has a foreach that creates some <a> tags using a number of ActionLinks. When one of the Links is clicked a listener method is triggered. This method then shows the ItemDetail using cycle.setPage("ItemDetail").

Now the question: since each link on the ItemList page shall display a different Item (using ItemDetail) I wonder how to pass the parameter (lets say the id (int)) of the Item to be displayed. How do you usually do this with tapestry? I probably just overlook the way to do it because I am not used to the Request cycle that is used with tapestry.

Any hint appreciated
