SimpleComboBox onlick lost all the options

[r_q_d]

Environement:
gwt-1.7.1
gxt2.1
java 1.5.0_21
windows xp
hosted mode

I have a very simple code here as following


public class MainEntryPoint implements EntryPoint {
public void onModuleLoad() {
Viewport viewport = new Viewport();
viewport.add(createForm());
RootPanel.get().add(viewport);
}

private static final String[] comboBoxValues=new String[]{"aaa","bbb","ccc"};
private SimpleComboBox<String> typeField;
private Widget createForm(){
FormPanel form = new FormPanel();
form.setHeading("SimpleComboBox test");

typeField=new SimpleComboBox<String>();
typeField.setFieldLabel("Type");
for(String type: comboBoxValues){
typeField.add(type);
}
form.add(typeField);
return form;
}
}
when I run the code, I got the page like this:

when I click one of the value, the release it, all the other options will be gone, now only one option left:

This was working on version gxt 1.2.4

Anyone has same problem?
