How to bind a List of POJO

Hi everyone,

In Vaadin 7, I’m trying to bind my ComboBox of phone numbers to a list of POJO nested in a POJO.
For exemple: I have PersonVo that contains a List phones; and PersonCommunicationVo contains the value of the phone number.

What I used for binding the others properties of PersonVo is:
BeanFieldGrouppersonBinder = new BeanFieldGroup(PersonVo.class);
personBinder.setItemDataSource(person);
myFormLayout.addComponent(personBinder.buildAndBind(“Firstname”, “firstName”));
myFormLayout.addComponent(personBinder.buildAndBind(“Country”, “country.name”));

Could you help me to do the same with a ComboBox with phones.

Thanks for the help!
