setItemCaption replacement in vaadin 8

is there a replacement for vaadin 8?

i want build generic form with comboBox which related List of data for comboBox.

so i need something like

[color=#555555]
<name="" value="">caption
[/color]

there are any solution for my problem?

Thank for your respon.

if i have a class

public class Language{
   String id;
   String name;
}

how i can bind id value if my combobox like

ComboBox<Language>;

i should show name, and setId in my combobox also my combobox is generic.

i think setItemCaptionGenerator is good because this method very flexible.

In Vaadin8 ComboBox the method you need setItemCaptionGenerator.
