Re: Display a String when null

[Vit Rozkovec]

Hi!
Maybe there is a better way, but I would do:

       add(new Label("country", new PropertyModel(this,
               "ipLocationInfo.country") {
           @Override
           public Object getObject() {
               String country = (String) super.getObject();
               country = country == null ? "unknown" : country;
               return country;
           }
       }));

Hi!

I'm quite new to Wicket and help with something easy, i guess.

I'm displaying some info on my page:

add(new Label("country", new PropertyModel(this,
"ipLocationInfo.country")));

The country information is sometimes null and then i would like to display
"unknown" instead. Is this easily managed or do i have to change the country
value of the ipLocationInfo object?

Regards Alex
