Hi I have the following domain object
public class User {
private String email;
private String firstName;
private String lastName;
private Account account;
public String getUserName() {
return this.account.getName();
}
public void setUserName(String username) {
this.account.setName(username);
}
}
I have a form with dropdownchoice.
final DropDownChoice<User> userChoice = new
DropDownChoice<Person>("userChoice",
new ListModel<User>(users),
new ChoiceRenderer<User>("userName", "userName"));
When the page loads i get this error!
org.apache.wicket.WicketRuntimeException: No get method defined for class:
class java.lang.String expression: userName
