Otherwise, I don't show anything here. I don't know if there is any better method to implement the optional link. So far I am checking the field and add an invisible link if the residence city is not saved. if (profile.getResidenceCity() == null) { PageLink cityLink = new PageLink("residenceCityLink", DummyPage.class); cityLink.setVisible(false); add(cityLink); ... ... } else { PageLink cityLink = getCityPage(profile.getResidenceCity()); add(cityLink); ... ... } There are many such kinds of links in my page. Please advise me if you know any better way to do this. Thanks. --Simon --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
