I don't understand why ExternalLink doesn't store the external href as
the model. It stores it in an href property. It seems to not follow
the normal wicket way.
This makes it difficult to do things like display a link only if the
model is not null. For instance:
add(new ExternalLink(web, new PropertyModel(service,web)) {
@Override
public boolean isVisible() {
if (getModelObject() == null) {
return false;
}
return super.isVisible();
}
});
The problem is that getModelObject() is always null, because the
PropertyModel is stored in the href property. And since isVisible()
is part of Component, the href property isn't accessible.
Any suggestions for a simple solution?
Thanks,

Re: ExternalLink doesn't use model?
Martijn,
Will do.
In the meantime, anyone have suggestions how to create a link to an
external web page that is only visible if the model is not null?
Thanks,

Re: ExternalLink doesn't use model?
Eelco,
Thanks. I was trying to do it as an anonymous class, but your idea is
simpler. Here's what I ended up with:
public class HidingExternalLink extends ExternalLink {
private static final long serialVersionUID = 1L;
public HidingExternalLink(final String id, final String href) {
this(id, href, null);
}
public HidingExternalLink(final String id, final IModel href) {
this(id,href,null);
}
public HidingExternalLink(final String id, final String href, final
String label) {
super(id, href, label);
setModel(new Model(href));
}
public HidingExternalLink(final String id, final IModel href, final
IModel label) {
super(id, href, label);
setModel(href);
}
public boolean isVisible() {
return getModelObject() != null;
}
}

Re: ExternalLink doesn't use model?
Anonymous class would be fine if you just pick one of the constructors.
