Hi, I using the gwt-sample-tab as a template.
I want to add another tab with a cell browser. My presenter should get data
from the database in the onBind method. ( or maybe onReset )
My problem is how to do this... if I instantiate the cellbrowser in the
onBind method..
Builder<PrintProviderMock> builder = new Builder<PrintProviderMock>(model,
null);
cellBrowser = builder.build();
I get a
com.google.gwt.user.cellview.client.CellBrowser has no default (zero args)
constructor. To fix this, you can define a @UiFactory method on the
UiBinder's owner, or annotate a constructor of CellBrowser with
@UiConstructor.
Sure, I need to create the cellbroser in the view...
@Inject
public PrintProvidersView(PrintProvidersUiBinder uiBinder) {
final PrintProviderModel model = new PrintProviderModel();
Builder<PrintProviderMock> builder = new Builder<PrintProviderMock>(model,
null);
cellBrowser = builder.build();
initWidget(uiBinder.createAndBindUi(this));
}
But how do I now update the model in the cellbrowser in the presenter ???
*ui.xml*
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent";>

<g:HTMLPanel>
<div align="center">
<c:CellBrowser defaultColumnWidth='300' ui:field='cellBrowser' />
</div>
</g:HTMLPanel>
</ui:UiBinder>
*View*
public class PrintProvidersView extends ViewImpl implements
PrintProvidersPresenter.MyView {
interface PrintProvidersUiBinder extends UiBinder<Widget,
PrintProvidersView> {
}
@UiField
CellBrowser cellBrowser;
@Inject
public PrintProvidersView(PrintProvidersUiBinder uiBinder) {
final PrintProviderModel model = new PrintProviderModel();
Builder<PrintProviderMock> builder = new Builder<PrintProviderMock>(model,
null);
cellBrowser = builder.build();
initWidget(uiBinder.createAndBindUi(this));
}
public CellBrowser getCellBrowser() {
return cellBrowser;
}
}
*Presenter*
public class PrintProvidersPresenter extends
Presenter<PrintProvidersPresenter.MyView, PrintProvidersPresenter.MyProxy> {
private final PrintProviderMockServiceAsync ppmockService =
GWT.create(PrintProviderMockService.class);
public interface MyView extends View {
public CellBrowser getCellBrowser();
}
@ProxyCodeSplit
@NameToken("PrintProviders")
@TabInfo(container = ApplicationPresenter.class, label = "Print Providers",
priority = 3)
public interface MyProxy extends
TabContentProxyPlace<PrintProvidersPresenter> {
}
@Inject
public PrintProvidersPresenter(EventBus eventBus, MyView view, MyProxy
proxy) {
super(eventBus, view, proxy);
}
@Override
protected void revealInParent() {
RevealContentEvent.fire(this, ApplicationPresenter.TYPE_SetTabContent,
this);
}
@Override
protected void onBind() {
super.onBind();
get data from database and update cellbrowser or if
possible instantiate cellbrowser here without getting the error about no
default (zero args) constructor
}
@Override
protected void onReset() {
super.onReset();
}
}
