Igor Vaynberg commented on WICKET-4468:
---------------------------------------
fix for this breaks wicket-cdi.
imagine a component that is visible only if the user is logged in. to do this
it overrides onconfigure() { setvisible(logins.getcurrentuser()!=null); }
where logins is a cdi bean.
Page#isPageStateless() is called as soon as the page is pulled from the page
store, which means now onconfigure() is called when wicket cdi retrieves the
page instance and before it is able to figure out what conversation to wrap the
page in.

> Key: WICKET-4468
> URL: https://issues.apache.org/jira/browse/WICKET-4468
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 1.5.5
> Reporter: Sebastian Gooren
> Assignee: Martin Grigorov
> Priority: Minor
> Fix For: 1.5.6, 6.0.0-RC1
>
>
> Stateful components which are not rendered (setVisible(false)) force the page
> to be stateful.
> Page#isPageStateless() visits all components to check
> Component#isStateless(), whether they are visible or not.
> Please change this so invisible components no longer force a page to be
> stateful.
