I wrote sample code. It should illustrate what the problem is. MaterialListBox not updated after the addition of items.

import gwt.material.design.client.ui.MaterialListBox;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.VerticalPanel;

public class Test implements EntryPoint {

  private MaterialListBox listBox;

  public void onModuleLoad() {
    listBox = new MaterialListBox();
    listBox.addItem("First");
    listBox.addItem("Second");
    listBox.addItem("Third");
    listBox.addItem("Fourth");
    listBox.addItem("Fifth");

    Button button = new Button("Add Six");
    button.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        listBox.addItem("Six");
      }
    });

    VerticalPanel panel = new VerticalPanel();
    panel.setSpacing(10);
    panel.add(listBox);
    panel.add(button);

    RootPanel.get("gwtContainer").add(panel);

  }
}

Ok we just solved the issue, we digged into the Material ListBox it seems its not reupdating the items when you call addItem(). Now we fixed it by calling onInitMaterialListBox() once the user add an item.
