Martin Grigorov commented on WICKET-5001:
-----------------------------------------
Wicket cannot know whether the page has state or not. If the page has no state
then it should use stateless component, i.e. page.isPageStateless() should
return true. In this case Wicket will execute onClick/onSubmit/... If the page
is stateful Wicket cannot make assumptions whether the component/behavior is
there or not.

> Key: WICKET-5001
> URL: https://issues.apache.org/jira/browse/WICKET-5001
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.4.0
> Environment: Java 7, GlassFish 3.1.2.2
> Reporter: bernard
> Priority: Critical
> Attachments: Testcase.zip
>
>
> Some efforts were made since 1.5 to reduce occurrences of
> PageExpiredException or at least the impact of it.
> Please see WICKET-4014
> With Wicket 6.4.0 it appears that a simple test case does not produce the
> expected results.
> The attached quickstart tests a page containing a form. The page does not
> have any meaningful state.
> Therefore, after session expiry Wicket should call the default constructor
> and execute form submit or link onclick without any problems.
> There is no difference in outcome that could be expected before and after
> expiry.
> In real life, if the page was constructed with an IModel constructor, of
> course the model would not exist after expiry but that could be handled in
> the default constructor that is called after expiry.
