In other words, what you should have done in the first place was
public class testChildPanel extends testSuperPanel {
public testChildPanel(String id) {
super(id);
get("childContainer").add(new Label("childLabel","Test!"));
}
}
So that the label would have actually been attached to the
webmarkupcontainer instead of the panel.
However the solution Martijn provided is much more elegant since it
eliminates the need for subclasses to be aware of implementation
details in the parent class.
