                var featureAttributes = results.features.attributes;
                for (att in featureAttributes) {
                    s = s + "<b>" + att + ":</b>  " + featureAttributes[att] + "<br />";

        dojo.addOnLoad(init);

    <input type="button" value="Get Details" onclick="execute(dojo.byId('stateName').value);" />
    <br />
    <br />
    <div id="info" style="padding:5px; margin:5px; background-color:#eee;">
    </div>
  </body>
</html>

I think is the 'MapaBase' service the one who is making the mistake but... I don't know anymore
I'll appreciate if anyone can help me... 🙂

Do you get anything in the js console when you run it?
Another thing to try is make sure the server is actually returning something by looking at the requests that the app sends to it.

If you're not sure how to do this take a look at firebug for firefox, dev console for IE8 or dev tools for chrome.
