I'm currently in the process of evaluating frameworks.  We are currently
using Wicket 1.4.

The ones I've looked at so far have been Vaadin, Tapestry 5.4, and Wicket
6.0.

Vaadin I ruled out for various reasons.

One of the problems that our users have complained quite a bit about is the
dreaded PageExpiration problem.

In Wicket 6.0 the issue is resolved somewhat by the framework recreating the
page and then issuing a redirect.

While understand why it does this

// If the page is stateful then we cannot assume that the listener interface
is
// invoked on its initial state (right after page initialization) and that
its
// component and/or behavior will be available. That's why the listener
interface
// should be ignored and the best we can do is to re-paint the newly
constructed
// page.

it's still not the solution we want.  The Ajax interaction should continue
on as normal.

Due to how Tapestry is architected, this is not an isssue.

In Wicket 1.4, I got around this somewhat by extending the
WebRequestCycleProcessor and recreating the request when a PageExpiration
was encountered.

It doesn't appear that I can carry this forward in Wicket 6.0.

I just want to make sure that I'm not missing anything.

Thanks
