Thanks Eelco!
I have tried it now. I'm getting this error:
wicket.markup.MarkupException: Component at markup stream index 1 failed
to advance the markup stream
[markup =
file:/F:/projects/jatak/tools/webtools/eclipse/com/jatak/webtools/web/gu
i/MemberPage.html, index = 1, current = 'null' (line 0, column 0)]

Can you see what that is about?

Subject: Re: [Wicket-user] autoAdd problem with HEAD
Yep. As we're doing header contributions in HEAD/ 1.1, we're depending
on the autoAdd feature. Add this:
/**
* @see wicket.MarkupContainer#autoAdd(wicket.Component)
*/
public boolean autoAdd(Component component)
{
return border.autoAdd(component);
}
to SimpleBorderedPage
I'll update the WIKI,
Eelco
