Hi Steve,

about your e-mail:

* I'm also interested in using the Google maps API from Seaside. I am far from
* an expert but it's possible to use an HttpRequest object to do this from the
* server.

I solve it with:    HTTPSocket httpGet: url

* My question is why would you do it from the server when you could make the
* request directly from the user's browser using the JavaScript API?

My input from user's browser , based on Magritte, is a string.
I'm not a javascript expert and i d'ont know how integrate it with seaside field.

In the Google documentation i found this javascript but how integrate it with my input data ?

    <script type="text/javascript">

    var map = null;
    var geocoder = null;

    function initialize() {
      if (GBrowserIsCompatible()) {
        map = new GMap2(document.getElementById("map_canvas"));
        map.setCenter(new GLatLng(37.4419, -122.1419), 13);
        geocoder = new GClientGeocoder();

    function showAddress(address) {
      if (geocoder) {
          function(point) {
            if (!point) {
              alert(address + " not found");
            } else {
              map.setCenter(point, 13);
              var marker = new GMarker(point);

  <body onload="initialize()" onunload="GUnload()">
    <form action="#" onsubmit="showAddress(this.address.value); return false">
        <input type="text" size="60" name="address" value="1600 Amphitheatre Pky, Mountain View, CA" />
        <input type="submit" value="Go!" />
      <div id="map_canvas" style="width: 500px; height: 300px"></div>

* I'm also wondering why you chose the static API instead of the dynamic one.
* I haven't played with the static version and I'm curious about its
* advantages.

When  i accept the user's browser i call the API for define the 'location' and after i browser a map for controll.
