In my Application i have a DropDownSelect which changes a Label onUpdate by
AjaxFormComponentUpdatingBehaviorThen there is a Button which tries access at
the selected item. In the real Webapp it works fine but when i test itwhen i
click the Button the selected Item is null.What I am doing wrong. Here the
HomePage:
public class HomePage extends WebPage { private static final long
serialVersionUID = 1L; private static final List<String> SEARCH_ENGINES =
Arrays.asList(new String[] { "Google", "Bing", "Baidu" }); //make Google
selected by default private String selected = "Google";
Model<String> model = new Model<String>() { public
String getObject() { return getSelected(); } };
private Label chosen=new Label("chosen", model); public HomePage(final
PageParameters parameters) { super(parameters); FeedbackPanel feedback=new
FeedbackPanel("feedback"); add(feedback); feedback.setVisible(true); // other
pages will set this to visible feedback.setEscapeModelStrings(false);
add(new Label("version",
getApplication().getFrameworkSettings().getVersion())); DropDownChoice<String>
listSites = new DropDownChoice<String>( "sites", new
PropertyModel<String>(this, "selected"), SEARCH_ENGINES);
Form<?> form = new Form<Void>("form"); final Button detailButton=new
Button("detailButton") { @Override public void onSubmit() {info(getSelected());
} }; detailButton.setOutputMarkupId(true); chosen.setOutputMarkupId(true);
listSites.add(new AjaxFormComponentUpdatingBehavior("onchange") {
@Override protected void onUpdate(AjaxRequestTarget target)
{ target.add(chosen);
target.add(detailButton); } });
form.add(chosen); add(form); form.add(listSites); form.add(detailButton); }
public String getSelected() { return selected; }
public void setSelected(String selected) { this.selected = selected; }}
and here the Test :
public class TestHomePage{ private WicketTester tester;
@Before public void setUp() { tester = new WicketTester(new
WicketApplication()); }
@Test public void homepageRendersSuccessfully() { //start and render the test
page tester.startPage(HomePage.class);
//assert rendered page class tester.assertRenderedPage(HomePage.class);
FormTester formTester = tester.newFormTester("form");
formTester.select("sites", 1);
tester.executeBehavior((AbstractAjaxBehavior)tester.getComponentFromLastRenderedPage("form:sites").getBehaviors().get(0));
tester.assertLabel("form:chosen", "Bing");
formTester.submit("detailButton");
tester.assertInfoMessages("feedback","Bing"); }}
i am using wicket 6.19.0
