Problem working with UiBinder

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a simple UiBinder widget class and .ui.xml related file.

 * NoopUiBinder.java:

package com.ofertaunica.webapplication.client.widgets;

import com.google.gwt.core.client.GWT;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.TextArea;
import com.google.gwt.user.client.ui.Widget;

public class NoopUiBinder extends Composite {

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

    @UiField
    TextArea field;

    interface NoopUiBinderUiBinder extends UiBinder<Widget, NoopUiBinder> {
    }

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

}

 * NoopUiBinder.ui.xml:
<!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">
    <ui:style>
    </ui:style>
    <g:HTMLPanel>
        <g:TextArea ui:field="field">Hello World</g:TextArea>
    </g:HTMLPanel>
</ui:UiBinder>

2. Create a simple testcase for this widget, as presented at 
wiki:SimpleUnitTest:

package com.ofertaunica.webapplication.widget;

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;

import com.octo.gwt.test.AbstractGwtTest;
import com.ofertaunica.webapplication.client.widgets.NoopUiBinder;

public class NoopUiBinderTest extends AbstractGwtTest {

    private NoopUiBinder binder;

    @Before
    public void setUp() {
        binder = new NoopUiBinder();
    }

    @Test
    public void testNotNull() {
        Assert.assertNotNull(binder);
    }

}

3. Run your test and get an Exception
I'm using Eclipse with Google Plugin, so just Run -> Run as ... -> Junit Test

What is the expected output? What do you see instead?
Test pass

What version of the product are you using? On what operating system?
gwt-test-utils 2.2, on Ubuntu 10.04

Please provide any additional information below.

I forgot to atach the stack trace for the exception I get:

I tried to annotate binder class variable with @Mock, but no success. Also, 
don't found usefull documentation on how to create the  addGwtCreateHandler() 
method.

Any tips?

Hi,

Actually, UIBinder is not supported for the moment. We are working on it for 
the next release. A roadmap will be published in the next couple of days.

Hi,

This is the list of your priorities :

- ext-GWT integration
- update to GWT 2.2.x
- UiBinder's support

We are currently focused on GXT integration which expect a lot of effort.
Update to GWT 2.2 should be quite easy (no more than 2 days of work)

A degraded version of UiBinder could be integrated in an easy way (only java 
declared widget would be accessed by gwt-test-utils).
A full version of UiBinder integration would be more difficult, since it will 
required to call gwt code generator (XML => java widget) manually.

You are more than welcome if you want to contribute (contact me by mail if you 
want)
