Hi !
I'm upgrading our application from Wicket 7.4.0 to 7.5.0 to benefit from the
security issue fix.
While doing this I encounter a problem with pages that extend other one and
define a <wicket:head> in their markup, for instance:
<wicket:head>
</wicket:head>
<wicket:extend>
<wicket:child/>
</wicket:extend>
The parent page have a defined markup with <head> and <wicket:child/>.
If the child page doesn't override getVariation() everything is fine, but if
it overrides it, I get the following error:
org.apache.wicket.markup.MarkupNotFoundException: Markup not found for
Component: [WicketHeadContainer [Component id = _header_]]
I guess it's related to WICKET-6231 because of getVariation().
I can provide a quickstart project where tests reproduce it.
It seems that a workaround is to change the way of defining the CSS by
overriding renderHead() + response.render(CSSHeaderItem.forCSS(...)), but I
have many classes to change so I'd like to know if a better way exists and
if the regression can be fixed ?
Of course I'd like to benefit from the security fix so I can't stay in
7.4.0.
Thanks !
