Hi,
I have this page where I have different components that need to be show
or hidden, depending on the value of some model fields. I implemented
this by overriding the isVisible method of the components. Now I was
wondering if there is a less verbose way of handling this? (I can't
group the components because it's not possible in the html markup).
item.add(new TextField("value") {
public boolean isVisible() {
OnlineBookingParametersArticle article =
(OnlineBookingParametersArticle) getParent().getModel().getObject();
return
article.getArticle().getNumberInStock() > 0;
}
});
item.add(new
Label("article.numberOfArticlesLabel", "Geen beschikbaar") {
public boolean isVisible() {
OnlineBookingParametersArticle article =
(OnlineBookingParametersArticle) getParent().getModel().getObject();
return
article.getArticle().getNumberInStock() <= 0;
}
});
item.add(new
Label("article.description"));
item.add(new
WebMarkupContainer("participantInfo") {
public boolean
isVisible() {
OnlineBookingParametersArticle article =
(OnlineBookingParametersArticle) getParent().getModel().getObject();
return
article.getArticle().getNumberInStock() > 0;
}
}
.add(new
Label("article.numberOfRequiredParticipants"))
.add(new
Label("article.maximumNumberOfParticipants")));
item.add(new Link("contactLink"){
@Override
public void onClick(){
//TODO : go to correct
page
}
@Override
public boolean isVisible() {
OnlineBookingParametersArticle article =
(OnlineBookingParametersArticle) getParent().getModel().getObject();
return
article.getArticle().getNumberInStock() <= 0;
}
});
