Re: Image widget not attached?

I removed the g:Image element from the UiBinder template and tried creating it in code, thus:

Image myImage;
myImage = new Image(url, 0, 0, width, height);
myHTMLPanel.add(myImage, myView);
This does not generate access to the URL (per FireBug, no network activity is generated). And I can find no evidence that the .add() did anything. What should I do to cause the image to be fetched from the URL and the Image widget to be attached to the desired div element?

                 <ui:text from='{strings.close}'/>

The div's container is the HTMLPanel at the root of the template.

    @UiField Image      myImage;
    myImage.setUrlAndVisibleRect(url, 0, 0, width, height);

By debugger inspection I see that at the point at which setUrl... is to be called, the Image has attached: false. What am I overlooking? (This is my first use of gwt-Image.)
