Creating menus using though UiBinder

Hi,

I am trying to create menus using UiBinder.

my ui.xml goes like

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>

<g:MenuBar vertical='true' ui:field='mainMenu'>
<g:MenuItem ui:field='item1'>Item 1</g:MenuItem>
<g:MenuItem ui:field='item2'>Item 2</g:MenuItem>
<g:MenuItem ui:field='sub' enabled='false'>
Submenu
<g:MenuBar vertical='true' ui:field='subMenu' />
</g:MenuItem>
</g:MenuBar>
</ui:UiBinder>

and java file goes like
package com.cadence.ams.client.ui;

import com.google.gwt.core.client.GWT;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.uibinder.client.UiHandler;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.HasText;
import com.google.gwt.user.client.ui.Widget;
import com.google.gwt.user.client.ui.MenuBar;
import com.google.gwt.user.client.ui.MenuItem;

public class testMenu extends Composite {

private static testMenuUiBinder uiBinder = GWT
.create(testMenuUiBinder.class);

interface testMenuUiBinder extends UiBinder<Widget, testMenu> {
}

public testMenu() {
initWidget(uiBinder.createAndBindUi(this));
}

@UiField MenuBar mainMenu;
@UiField MenuItem item1;
@UiField MenuItem item2;
@UiField MenuBar subMenu;
@UiField MenuItem sub;


@UiHandler("item1")
void onClick(ClickEvent e) {
Window.alert("item1!");
}
}

And while compiling I am getting error.
[ERROR] The prefix "g" for element "g:MenuBar" is not bound.
[ERROR] Error parsing XML (line 1): The prefix "g" for element
"g:MenuBar" is not bound.

I searched for internet and google group but could not get the
solution.
I am very new to GWT, in case of any stupid mistake also do let me
know.


Help will be very much appreciated.
Thanks,
Chakresh
