I'm building a flex (mobile) project. When I want to parse the result of a webservice I'm having (some frustrating & probably stupid) issues.When I get one object back I need to use one method of parsing, while when I receive multiple objects (ArrayCollection) from the webservice I need to use another method of parsing which is quite annoying. I've included a code example which accents the problem. Further on I've included a possible solution which is in my eyes quite bad. You can also find an XML outline and some output data. Thanks for any feedback.Code:\[code\]public function saveData(event):void{ locationDAO = new LocationDAO(); parameterDAO = new ParameterDAO(); for each (var datObj:Object in event.result.Envelope.Body.pollResponse.locs) { var data
