[fother]

when set a value to combobox the hidden field don't received the value.. I need select the item in combobox to my hidden field receveid the value.. the problem:

my form have a combobox that have the country that the person live.. when the user go update your profile.. I need reset this field and do the user to select you country again...

		ListStore<TestModel> store = new ListStore<TestModel>();

		TestModel model = new TestModel();
		model.setCodigo(1);
		model.setNome("name 1");

		TestModel model1 = new TestModel();
		model1.setCodigo(2);
		model1.setNome("name 2");

		store.add(model);
		store.add(model1);

		FormPanel form = new FormPanel();

		ComboBox<TestModel> combo = new ComboBox<TestModel>();

		combo.setDisplayField("nome");
		combo.setValueField("codigo");
		combo.setName("comboBox");
		combo.setValue(model);

		form.add(combo);

		RootPanel.get().add(form);

TestModel.java

public class TestModel extends BaseModel {

	public Integer getCodigo() {
		return get("codigo");
	}

	public String getNome() {
		return get("nome");
	}

	public void setCodigo(Integer codigo) {
		set("codigo", codigo);
	}

	public void setNome(String nome) {
		set("nome", nome);
	}

}

wait.. setValueField() ???? I will test

[fother]

add to the code, and you can see that the hidden field continue with the value empty..

combo.setValueField(model.getCodigo().toString());

Thanks for reporting.

In combobox...

private String loadingText = "Loading...";

????

in properties..

# ComboBox
comboBox_loading=Loading...

[fother]

to solve this problem....

    if (valueField != null) {
      hiddenInput = Document.get().createHiddenInputElement().cast();
      hiddenInput.setName(getName() + "-hidden");
      parent.appendChild(hiddenInput);
      updateHiddenValue(); // add this line or use other logic
    }

We already have a fix for this ready. Your suggested fix isnt fixing the hole issue.

[fother]

hmm...

[fother]

now appears other problem..

	public void onModuleLoad() {

		ListStore<TestModel> store = new ListStore<TestModel>();

		TestModel model = new TestModel();
		model.setCodigo(1);
		model.setNome("name 1");

		TestModel model1 = new TestModel();
		model1.setCodigo(2);
		model1.setNome("name 2");

		store.add(model);
		store.add(model1);

		final FormPanel form = new FormPanel();
		form.setAction("Example");
		form.setMethod(Method.POST);

		ComboBox<TestModel> combo = new ComboBox<TestModel>();
		combo.setStore(store);
		combo.setFieldLabel("xxx");
		combo.setDisplayField("nome");
		combo.setValueField("codigo");
		combo.setName("comboBox");
		combo.setValue(model);
		combo.setValueField(model.getCodigo().toString());

		Button button = new Button("button");
		button.addSelectionListener(new SelectionListener<ComponentEvent>() {

			@Override
			public void componentSelected(ComponentEvent ce) {

				form.submit();

			}

		});

		form.add(combo);
		form.add(button);

		RootPanel.get().add(form);
	}

Example.java

	@Override
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		System.out.println(request.getAttribute("comboBox-hidden"));

	}

Click to the button, return null. OK - the bug
Change to "name 2" in combo box, click to the button, return null..

You can test too, with your new code this? Because when the user will go update your profile.. he can't more save... same change the value.

thanks
