Hmmm, no. I need more details.

Another thing you can consider is using markup inheritence (Phil described that here: http://jroller.com/page/pKulak/20050712, and there is the template example in wicket-examples HEAD), which is much easier to use.

I have tried it now. I'm getting this error:

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,

Hi

I have a pretty simple program with a border (as described on wiki: How to create consistent page layouts using Borders
<http://wicket.sourceforge.net/wiki/index.php/Consistent_page_layout_usi
ng_borders>).
On one page there is a button that makes the server calculate some stuff and just stay on the page to display the results. After upgrading to HEAD version, I am getting this error:

wicket.WicketRuntimeException: If the root exception says something
like "A child with id '_header' already exists"than you most likely
forgot to override autoAdd() in your bordered page component.

Do I need to override autoAdd() somewhere? If so, where and how?

I tried the "re-use strategy" in MarkupContainer, but with the same results.
