Gerolf Seitz commented on WICKET-1173:
--------------------------------------

i think you somehow misuse the bodyContainer. for one, the wicket:body tag is 
not even rendered when you run the application in standard deployment mode (see 
MarkupSettings->stripWicketTags).

as for your example:
<wicket:border>
<a wicket:id="hideLink">Hide/Show</a>
<wicket:body></wicket:body>                                     
</wicket:border>

i'd suggest wrapping the body in a separate container and hiding/showing the 
container instead:
(code based on your example)
HTML:
<wicket:border>
<a wicket:id="hideLink">Hide/Show</a>
<div wicket:id="bodyWrapper"><wicket:body></wicket:body></div>
</wicket:border>

JAVA:
public class HideableBorder extends Border {
        private WebMarkupContainer wrapper 

        public HideableBorder(String name) {
                super(name);
                addHideLink();
                wrapper= new WebMarkupContainer("bodyWrapper");
                wrapper.setOutputMarkupPlaceholderTag(true);
                wrapper.setVisible(false);
        }

        private void addHideLink() {
                add(new AjaxLink("hideLink") {
                        public void onClick(AjaxRequestTarget target) {
                                wrapper.setVisible(!wrapper.isVisible());
                                target.addComponent(wrapper);
                        }
                });
        }
}
