    Default Unanswered: Empty combo box when filling it with a RPC service

    Unanswered: Empty combo box when filling it with a RPC service


    In a UiBinder file, I define a combo box in a HBoxLayoutContainer (along with some other components that are displayed fine):
    Code:
    <container:child layoutData="{boxLayoutData_MarginRight}">
      <form:FieldLabel text="Granularity">
        <form:widget>
          <form:ComboBox ui:field="granularityCombo"
              allowBlank="false" triggerAction="ALL"/>
        </form:widget>
      </form:FieldLabel>
    </container:child>
    In the Java code, I define it as:
    Code:
    GranularityProperties m_props = GWT.create( GranularityProperties.class );
    ListStore<Granularity> m_store = new ListStore<Granularity>( m_props.key() );
    
    @UiField(provided = true)
    ComboBox<Granularity> granularityCombo;
    and in the asWidget() method, I create it:
    Code:
      granularityCombo = new ComboBox<Granularity>( m_store, m_props.name() );
      GranularityServiceAsync service = (GranularityServiceAsync) GWT.create( GranularityService.class );
      final AsyncCallback<List<Granularity>> callback = new AsyncCallback<List<Granularity>>()
      {
         @Override
         public void onSuccess( List<Granularity> result )
         {
            System.out.println("OK with " + result);
            m_store.addAll( result );
         }
    
         @Override
         public void onFailure( Throwable caught )
         {
            // Log error? Display message...
            System.out.println("Oops " + caught);
         }
      };
      service.getGranularities( callback );
    My service works, I get data in the result parameter.

    But the combo box is empty, displayed as a button with a >> content, showing a tiny empty list.
    Does the combo box support filling the store asynchronously as above?
    The GXT Demos/examples get their data from the client side, so it is hard to tell if I make a mistake or if that's a bug in the Beta 2.

    I have several combo boxes working with data from RCP calls.

    But, I don't use UiBinder ...

    The problem has disappeared with Beta3.
    Thanks.
