Hi Yasser,
Thanks for your useful suggestion!
It works with:
public class RegisterAction {
...
public Country getSelectedCountryObject(String selectedCountry) {
for (Country c : countryList) {
if (String.valueOf(c.getCountryId()).equals(selectedCountry))
return c;
}
return new Country(0, "");
}
...
}
