ComboBox doesn't update

Vaadin 6 / 7 / 8

Hi, I have a Combobox which contains 3 items (id : 1,2,3). I can select them via the mouse. By default, my combobox is on blank field (no item selected). When I want to change its value via a button (setValue(1) ,for example), my ComboBox doesn’t update !
I don’t understand this behavior ! Someone can help me ? :slight_smile:

Can you post a minimal code sample?

[code]
public void construireListeExecutions(List executions) {
//On remet le composant à zéro
listeDeroulanteExecutions.removeAllItems();
listeDeroulanteExecutions.setNullSelectionAllowed(false);

    //Pour chaque execution, creation d'un item dans la liste
    for (Execution execution : executions) {
        listeDeroulanteExecutions.addItem(execution.getId());
        listeDeroulanteExecutions.setItemCaption(execution.getId(), execution.getNom());
    }
    System.out.println("before "+listeDeroulanteExecutions.getValue());
    listeDeroulanteExecutions.setValue(2);
    System.out.println("after "+listeDeroulanteExecutions.getValue());
}

[/code]Anyway, when I make a SetValue(), in reality, the value doesn’t change…
Resultat :
before 1
after 1

Ok, what does execution.getId() return (Which type)?
Because basically, this should work.

Thanks for quick answer !
But I resolved my problem. My Ids on my combobox are Long, not Integer… So I replace 2 to 2L and it works correctly !
thanks Tom :wink: have a good day
