I'm currently evaluating component based frameworks, as we are using Wicket, and one of the problems we encounter is Ajax interactions after the http session has expired.
If a user clicks on a component that is Ajax enabled - the framework throws a PageExpiration exception. For most applications, we want the request to still continue. The HelloWorld example from Tapestry doesn't appear to experience this. My questions are - For persistent data on a page where is this serialized to? - Are all Ajax interactions safe in this manner, form buttons, links, etc
