Thank you.

I don't know how you pass this link to Google Maps?

If you want to generate an URL-String for a given AJAX updater you can
write something like:

  (html updater id: 'foo'; callback: [ :r | r render: 'bar' ]; url) asString

Is this what you want? Or do you also need an XHTML snippet with an
anchor tag around that?

  (html javascript render: [ :h1 |
    h1 anchor
       onClick: (h1 updater
          id: 'someId';
          callback: [ :h2 | h2 render: 'Hello World' ]);
       with: 'Click Me' ]) asJavascript

I guess you get the idea ;-)
