something like this:
class panelwithanychild extends panel implements icomponentresolver {
public panelwithanychild(string id) {
super(id);
}
public boolean resolve(final MarkupContainer container, final
MarkupStream markupStream,
final ComponentTag tag) {
if (container==this&&((WicketTag)tag).getId().equals("marker"))
{
if (size()!=1) { throw new IllegalStateException("need exactly
one child"); }
Component child=iterator().next();
child.beforeRender(); child.render(); return true;
}
return false;
}
}
panelwithanychild.html
<wicket:panel><div wicket:id="marker"></div></wicket:panel>
then just
markupcontainer pc=new panelwithanychild("container");
add(pc);
pc.add(p);

I think I'm going to have to use Panel instead of Border because it is not
just a decoration but placement of multiple components.
How do I write a ThreePanelLayout which lays out any 3 panels with the
constructor ThreePanelLayout(Panel a, Panel b, Panel c). For obvious reasons
I do not want to have the callers to know what they must name their panels.
Since I dont know the names of the Panels, how do I write a
ThreePanelLayout.html?
Thanks
Ravi.

depends on how much control you need over the markup that is already in
datatable.html. if what is in there doesnt bother you you have a few
options
border that you put a datatable in, or a panel that adds datatable as a
child
if you dont like what is inside datatable.html then you simply replace it
with whatever you want in your subclass.html.
