Template field and owner field types don't match

[Jeff Chimene]

Hi:

I'm trying to figure out how to create a custom widget in RC2, based on
ClickyLink.

The error I get is
"Template field and owner field types don't match:
com.google.gwt.dom.client.Element != com.my.office.client.view.CloseButton"

I'm sure message this means something to someone.

the ui.xml file is
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent";>
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
  xmlns:gwt='urn:import:com.google.gwt.user.client.ui'
  xmlns:fori="urn:ui:com.my.office">
    <ui:style>

    </ui:style>
        <my:CloseButton ui:field="closeBtn"/>
</ui:UiBinder>

There is a class that is ClickyLink renamed to CloseButton minus the call to
addDomHandler (which doesn't compile)
public class CloseButton extends Widget {

    public CloseButton() {
        setElement(DOM.createButton());
        sinkEvents(Event.ONCLICK);
    }
}

The instantiation is:
public class TaskView extends Composite {
    @UiTemplate("CloseButton.ui.xml")
    interface TaskBinder extends UiBinder<Widget, TaskView> {}

    private static TaskBinder    taskBinder    =
GWT.create(TaskBinder.class);

    @UiField CloseButton                    closeBtn;

    public TaskView() {
        initWidget(taskBinder.createAndBindUi(this));
    }
}

Adding "provided=true" and an initializer merely generates another
compile-time error.

I thought I'd have to use the @UiFactory annotation (a la CricketScores),
but ClickyLink doesn't do this.

I'm sure this is a relatively minor problem which someone with experience in
creating custom widgets can easily answer.
