> error from WebPage # reportMissingHead
> --------------------------------------
>
> Key: WICKET-5955
> URL: https://issues.apache.org/jira/browse/WICKET-5955
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 6.20.0, 7.0.0-M6
> Reporter: francois
> Assignee: Sven Meier
> Priority: Minor
> Fix For: 7.0.0, 6.21.0
>
> Attachments: quickstart.zip
>
>
> Use case
> -----------
> on 'PageWithForm', after having filled the form, the user press a submit button.
> A cookie has to be updated.
> To trigger the update, a session attribute is set to false.
> Then the user is redirected to a page : setResponsePage( new ResultPage() )
> ResultPage extends Skeleton
> In the Skeleton page, if the session attribute is set to false, the cookie is updated.
> Then a NonResettingRestartException is thrown.
> Problem
> -----------
> When I throw a NonResettingRestartException() in a page where I also override renderHead()
> I get an error from WebPage # reportMissingHead
> You probably forgot to add a <body> or <head> tag to your markup since no Header Container was
> found but components were found which want to write to the <head> section.
> <script type="text/javascript" src="./resource/org.apache.wicket.resource.JQueryResourceReference/jquery/jquery-1.11.3-ver-1435772778000.js"></script>
> <link rel="canonical" href="https://localhost:8443/wicket/bookmarkable/com.quickstart.PageWithForm" />
> but body and head tags are presents.
> Sven Answer
> -----------
> you're SkeletonPage is interrupting its normal page rendering (#onInitialize() being triggered late from WebPageRenderer).
> Thus in WebPage#validateHeaders() the page doesn't find its HtmlHeaderContainer, which it expects to exists already if rendering succeeded successfully.
> So a) the error message is misleading and b) we may be able to improve this (e.g. checking #hasBeenRendered() before validating the headers).
