here is part of the code called when opening conmbobox:

deviceCombo.addForward("onOpen", this, "onRefreshDevice", deviceCombo);

public void onRefreshDevice(Event event) {
Combobox devicesCombo = (Combobox) event.getData();
devicesCombo.getChildren().clear();
Device selected = phone.getDevice();

Comboitem item = null;

boolean chooseNextAsDefault = (selected == null);

for (Device device : this.profile.getDevices()) {
item = new Comboitem();
item.setValue(device);
item.setLabel(device.getVisibleName());

devicesCombo.appendChild(item);
if (selected != null && device.getId() == selected.getId()) {
devicesCombo.setSelectedItem(item);
} else if (chooseNextAsDefault) {
devicesCombo.setSelectedItem(item);
this.phone.setDevice(device);
chooseNextAsDefault = false;
}
}
}
