error from WebPage # reportMissingHead
Hi Wicketers,
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.
Environment:
-----------
WIcket 7.0.0-M6
Do you have any idea why ?
Thanks
Fran�ois

Hi,
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).
Please create a Jira issue for this.
For now you could just override #onConfigure() instead of #onInitialize().
Have fun
Sven
