There is another solution, implementing a StringConverter. It's very useful for objects:

public class Product {

    private String code;
    private String name;

    public Product(String code, String name) {
        this.code = code;
        this.name = name;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

Converter implementation:

public class ProductConverter extends StringConverter {

    /** Cache of Products */
    private Map productMap = new HashMap();

    @Override
    public String toString(Product product) {
        productMap.put(product.getName(), product);
        return product.getName();
    }

    @Override
    public Product fromString(String name) {
        return productMap.get(name);
    }

}

Code in view:

    ComboBox cboProducts  = new ComboBox;
    cboProducts.setConverter(new ProductConverter());
    cboProducts.getItems().addAll(serviceManager.getProductList());

To get the value of the product, you can call getValue() method:

cboProducts.getValue()
