In general terms:
class A extends Panel {
private ABMediator mediator;
//...
add(new AjaxLink<Void>("theLink") {
public void onClick(AjaxRequestTarget target) {
mediator.callIntoB(target);
});
}
}
class B extends Panel {
// ...
public methodForTheMediator(AjaxRequestTarget target) {
// Do something
target.addComponent(someBComponent);
}
}
class ABMediator {
private A a;
private B b;
// ...
public void callIntoB(AjaxRequestTarget target) {
b. methodForTheMediator(target);
}
}
You could also leave out passing around the target and instead get it using
AjaxRequestTarget.get(). As you see, the method invoked on B is public in this
case.
