Vaadin combox BeanContainer - retrieve bean

I’m using an beanContainer to fill an combobox en to show the “loginName” as the selection field.


public class UserDTO extends Observable implements Serializable {
private static final long serialVersionUID = 1L;
private int userId;
private String loginName;
private String password;
private String firstName;
private String lastName;
private AddressDTO address;
private boolean privacyAddress;
private String pictureLocation;
private Date birthDate;
private RightDTO right;
private String email;
private String telephone;
private boolean privacyTelephone;
private String mobile;
private boolean privacyMobile;
private int minLimit;
private int maxLimit;
private int balance;
private boolean active;

//filling the combobox with UserDTO's by BeanContainer
    BeanContainer<String, UserDTO> beanContainer = new BeanContainer<String, UserDTO>(
    ArrayList<UserDTO> solvers = pc.retrieveSolvers();
    for (int i = 0; i < solvers.size(); i++) {
        System.out.println("solver = " + solvers.get(i));

I would like to create an combobox where I can select the UserDTO. The name in the combobox that I would like to show is the LoginName of the UserDTO, but I would like to retrieve the selected UserDTO depending on what is selected in the Combobox. When I use combobox.getValue() I get a String and not the UserDTO. What is the best way to do so?

Here’s a basic example
of using a ComboBox to select an item from a BeanItemContainer. Does that help or is your case with BeanContainer somehow different?
