Hello,
I am trying to implement Bean validation and integrate it with Editors.
I have following code base:
*DomainConfigComponent.java*
import com.github.gwtbootstrap.client.ui.ValueListBox;
import com.google.gwt.editor.client.HasEditorErrors;
import com.google.gwt.editor.client.IsEditor;
import com.google.gwt.editor.ui.client.adapters.ValueBoxEditor;
import com.google.gwt.user.client.ui.IsWidget;
import com.hat.weevify.client.domain.DomainConfig;
public interface DomainConfigComponent extends IsWidget,
HasEditorErrors<DomainConfig> {
void setPresenter(Presenter presenter);
public interface Presenter {
}
@Path("id")
IsEditor<ValueBoxEditor<Integer>> getId();
@Path("textDirection")
ValueListBox<String> getTextDirectionEditor();
@Path("name")
IsEditor<ValueBoxEditor<String>> getSiteNameEditor();
@Path("siteEmail")
IsEditor<ValueBoxEditor<String>> getSiteEmailEditor();
@Path("contactEmail")
IsEditor<ValueBoxEditor<String>> getContactEmailEditor();
@Path("favicon")
IsEditor<ValueBoxEditor<String>> getFaviconEditor();
@Path("host")
IsEditor<ValueBoxEditor<String>> getHostEditor();
@Path("landingPage")
IsEditor<ValueBoxEditor<String>> getLandingPage();
@Path("defaultLanguageId")
public ValueListBox<Integer> getDefaultLanguageEditor();
public void reset();
public Boolean save();
}
*DomainConfigComponentImpl.java*
import java.io.IOException;
import java.util.List;
import com.github.gwtbootstrap.client.ui.FluidRow;
import com.github.gwtbootstrap.client.ui.Form;
import com.github.gwtbootstrap.client.ui.IntegerBox;
import com.github.gwtbootstrap.client.ui.TextBox;
import com.github.gwtbootstrap.client.ui.ValueListBox;
import com.google.gwt.core.client.GWT;
import com.google.gwt.editor.client.EditorError;
import com.google.gwt.editor.client.IsEditor;
import com.google.gwt.editor.ui.client.ValueBoxEditorDecorator;
import com.google.gwt.editor.ui.client.adapters.ValueBoxEditor;
import com.google.gwt.text.shared.Renderer;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Widget;
import com.hat.weevify.client.domain.Language;
import com.hat.weevify.client.system.SystemData;
public class DomainConfigComponentImpl implements DomainConfigComponent {
interface DomainConfigComponentImplUiBinder extends UiBinder<FluidRow,
DomainConfigComponentImpl> {
}
private static DomainConfigComponentImplUiBinder uiBinder =
GWT.create(DomainConfigComponentImplUiBinder.class);
private Presenter presenter;
private final FluidRow settingsContainer;
@UiField
Form siteConfigForm;
@UiField
IntegerBox id;
@UiField(provided = true)
ValueListBox<String> textDirection;
@UiField(provided = true)
ValueListBox<Integer> defaultLanguage;
@UiField
TextBox siteName;
@UiField
TextBox host;
@UiField
TextBox siteEmail;
@UiField
TextBox contactEmail;
@UiField
ValueBoxEditorDecorator<String> favicon;
@UiField
TextBox landingPage;
public DomainConfigComponentImpl() {
textDirection = new ValueListBox<String>(new Renderer<String>() {
public void render(String object, Appendable appendable) throws
IOException {
appendable.append(render(object));
}
public String render(String object) {
return object;
}
});
defaultLanguage = new ValueListBox<Integer>(new Renderer<Integer>()
{
public String render(Integer object) {
for (Language lang :
SystemData.getInstance().getLanguageList()) {
if (lang.getId() == object) {
return lang.getName();
}
}
return null;
}
public void render(Integer object, Appendable appendable)
throws IOException {
String s = render(object);
appendable.append(s);
}
});
settingsContainer = uiBinder.createAndBindUi(this);
}
public Widget asWidget() {
return settingsContainer;
}
public void setPresenter(Presenter presenter) {
this.presenter = presenter;
}
public void reset() {
// TODO implement reset method
}
public Boolean save() {
// TODO Auto-generated method stub
return null;
}
public IsEditor<ValueBoxEditor<Integer>> getId() {
return id;
}
public ValueListBox<String> getTextDirectionEditor() {
return textDirection;
}
public ValueListBox<Integer> getDefaultLanguageEditor() {
return defaultLanguage;
}
public IsEditor<ValueBoxEditor<String>> getSiteNameEditor() {
return siteName;
}
public IsEditor<ValueBoxEditor<String>> getSiteEmailEditor() {
return siteEmail;
}
public IsEditor<ValueBoxEditor<String>> getContactEmailEditor() {
return contactEmail;
}
public IsEditor<ValueBoxEditor<String>> getFaviconEditor() {
return favicon;
}
public IsEditor<ValueBoxEditor<String>> getHostEditor() {
return host;
}
public IsEditor<ValueBoxEditor<String>> getLandingPage() {
return landingPage;
}
public void showErrors(List<EditorError> errors) {
if (!errors.isEmpty()) {
favicon.showErrors(errors);
}
}
}
And in activity I have declared interface
interface DomainEditorDriver extends
> SimpleBeanEditorDriver<DomainConfig, DomainConfigComponent> {
> }
>
and snippet that is actually performing validations
Validator validator =
> Validation.buildDefaultValidatorFactory().getValidator();
> Set<ConstraintViolation<DomainConfig>> violations =
> validator.validate(currentDomainEditor.flush());
>
> if (!violations.isEmpty()) {
> @SuppressWarnings({ "rawtypes", "unchecked" })
> Iterable<ConstraintViolation<?>> violations2 =
> (Iterable<ConstraintViolation<?>>) (Set) violations;
> currentDomainEditor.setConstraintViolations(violations2);
>
> return;
> }
>
If I don't put
if (!errors.isEmpty()) {
favicon.showErrors(errors);
}
in DomainConfigComponentImpl showErrors method, favicon editor decorator
does not display errors even if there are errors with favicon property. So
basicaly constraint violations does not propagate to other editors.
Any help is welcome.
Thanks,
Milan
