    Is it possible to call a web service from javascript within a Design Studio form?  We would like to add validation to data entry on a Design Studio form by utilizing a web service.

        How do you retrieve the xml returned by the web service? The web service is ony useful if we can call the service and parse the return xml in a respectable timeframe to present an error message to the end user if their data entry is invalid.

          Same way you parse the return from a DME or AGS call.

           var sInfo = portalWnd.httpRequest(URLStr);
            var vObjDMEXML = new portalWnd.DataStorage(sInfo);
           var vRecords = vObjDMEXML.document.getElementsByTagName("RECORD");
