Hello everyone,
I am working on a page which needs a feature of optional link. for example,
I have a html file as shown blew:
<div wicket:id="profile">
<a wicket:id="residenceCityLink">
<span wicket:id="residenceCItyLabel">
</a>
</div>
What I want is: if a user's profile has a valid residence city field, I will
show the city link and label.
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.
