 *
 * see: http://code.google.com/intl/it/apis/maps/index.html
 * get a key @ http://code.google.com/intl/it/apis/maps/signup.html
 *
 * INPUT, TEXTAREA, and SELECT are the only tags allowed
 *
 * final value is stored by Google API into two hidden fields called
 * lat (latitude)
 * lng (longitude)
 * NO DIFFERENT NAME IS SUPPORTED and they must be stored into the respective fields of AnagraphicalData in order to maximize response speed
 * thus
 * REMENBER to update your anagraphical data save action
 * add to additionalParams serialized map fields lng and lat
 * data.getAdditionalParams().put("lng", pageState.getEntry("lng").stringValueNullIfEmpty());
 * data.getAdditionalParams().put("lat", pageState.getEntry("lng").stringValueNullIfEmpty());
 * and make action
 * pageState.addClientEntry("lat", getAdditionalParams().get("lng"));
 * pageState.addClientEntry("lng", getAdditionalParams().get("lat"));
 *
 * NB: it can works only if intranet can access internet (main google js are accessed via web)
