Sure, here it is below. Test selects a non-default value from
'publicLocationChoices' drop down. Problems are:
-on form submit, LocationSelectionPanel.convertInput() is not called (have
breakpoint there)
-in debugger, I can see dropDown's rawInput changing on form submit, but
model's object ('data') value is never updated
Test
public void testLocationSelectionPanel_SelectCohost() {
final WicketTester t = getTester();
final VirtualEventFormBean formBean = new VirtualEventFormBean();
formBean.setEventId(EVENT_ID);
formBean.setOrganizerId(currentUser.getId());
final EventLocation initialLocation =
virtualEventService.getCustomSpaceEventLocation(currentUser.getId());
formBean.setLocation(initialLocation);
LocationSelectionPanelTestPage p = new
LocationSelectionPanelTestPage(formBean);
t.startPage(p);
t.assertRenderedPage(LocationSelectionPanelTestPage.class);
DropDownChoice publicLocationsChoice = (DropDownChoice)
t.getComponentFromLastRenderedPage("form:location:publicLocationChoices");
//selecting component
FormTester ft = t.newFormTester("form");
//select cohost
ft.select("location:publicLocationChoices", 1); //select 1st public
location
//submit
ft.submit();
EventLocation newLocation = p.getFormBean().getLocation();
assertNotSame(initialLocation, newLocation);
assertTrue(newLocation instanceof PublicEventLocation);
}
Test Page
public class LocationSelectionPanelTestPage extends AbstractWebPage {
@SpringBean private VirtualEventService virtualEventService;
private final VirtualEventFormBean formBean;
private CompoundPropertyModel model;
public LocationSelectionPanelTestPage(VirtualEventFormBean formBean) {
assert formBean != null;
this.formBean = formBean;
model = new CompoundPropertyModel(formBean);
Form form = new Form("form", model);
add(form);
//location selection
final CustomSpaceEventLocation organizerLocation =
virtualEventService.getCustomSpaceEventLocation(formBean.getOrganizerId());
//assemble cohost models
List<CustomSpaceEventLocation> cohostLocations = new
ArrayList<CustomSpaceEventLocation>();
for (Serializable cohostId : formBean.getCohosts()) {
CustomSpaceEventLocation cohostLocation =
virtualEventService.getCustomSpaceEventLocation(cohostId);
cohostLocations.add(cohostLocation);
}
LocationSelectionPanel locationSelectionPanel = new
LocationSelectionPanel(
"location",
organizerLocation,
cohostLocations,
virtualEventService.getPublicEventLocations(),
formBean);
form.add(locationSelectionPanel);

public VirtualEventFormBean getFormBean() {
