Hi,
in Ninja, you could do something like this
@Component
Katana katana;
@Inject
AjaxResponseRenderer ajaxResponseRenderer;
onActionFromNinjaLink() {
ajaxResponseRenderer.addRender(katana.getZone.getClientId(),
katana.getZone());
}
with a getter in the Katana component that returns the zone. Or, if
katana is not in Ninja, via
@InjectPage
Page pageThatContainsKatana;
and then pageThatContainsKatana.getKatana().getZone()...
(I don't know if it's possilbe to inject components directly so you
don't have to inject the page)

Do you mean parent/child like in class inheritance? Why would you do
that? Ninja and Katana are totally different things. Or did I get you
somehow wrong?
