If it's very simple, a straight get("path") may be OK, but
generally it's better to use visitors and/or findParent to
not depend so much on the exact component hierarchy.

class StatusMessage extends Label {
public StatusMessage() {
super("message", "If you see this message wicket is
properly configured and running");
}
}

getPage().visitChildren(StatusMessage.class, new
IVisitor<Component>() {
public Object component(Component component) {
component.setDefaultModelObject("Deleted");
}
});
