RecordClickHandler is NOT working for picklist!

When setting picklist properties on a ComboBoxItem, the addRecordClickHandler does not get fired upon click.

Here's a simple TestCase to show the problem.
The TestDS is a GwtRpcDataSource in which implementation, the fetch returns a list of (Integer id, String name);

Code:

package org.test.client;



import com.google.gwt.core.client.EntryPoint;

import com.google.gwt.user.client.Window;

import com.smartgwt.client.widgets.form.DynamicForm;

import com.smartgwt.client.widgets.form.fields.ComboBoxItem;

import com.smartgwt.client.widgets.grid.ListGrid;

import com.smartgwt.client.widgets.grid.ListGridField;

import com.smartgwt.client.widgets.grid.events.RecordClickEvent;

import com.smartgwt.client.widgets.grid.events.RecordClickHandler;

import org.test.client.ds.TestDS;



public class MainEntryPoint implements EntryPoint {



    private final DynamicForm form = new DynamicForm();

    private final TestDS datasource = new TestDS();



    public MainEntryPoint() {

    }



    @Override

    public void onModuleLoad() {

        ComboBoxItem combo = new ComboBoxItem("Test");

        combo.setValueField("id");

        combo.setDisplayField("name");

        combo.setOptionDataSource(datasource);



        ListGridField idField = new ListGridField("id");

        ListGridField nameField = new ListGridField("name");

        combo.setPickListFields(idField, nameField);



        ListGrid pickListProperties = new ListGrid();

        pickListProperties.addRecordClickHandler(new RecordClickHandler() {



            @Override

            public void onRecordClick(RecordClickEvent event) {

                Window.alert("CLICKED");

            }

        });

        combo.setPickListProperties(pickListProperties);



        form.setItems(combo);

        form.draw();

    }

}

It doesn't work regardless of browser!
