[Seaside] Using Comet to push PNG files?

[santiago robles]

Hello, I tested this and it worked.

    html image id: 'lala';
         url: SUAllTestLibrary / #logoGif.

    html anchor onClick: (html element id: 'lala';
            replace: [:render | render image id: 'lala';
                     url: SUAllTestLibrary / #demoGif]);
         with: 'change'.

So I suppose that your error is that you didn't use a block to render the
new image.
Hope that helps
Santiago
