I may agree with you, but in that case, how do you explain that the demo code from the "restaurant" sample application works:
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";> <mx:HTTPService id="srv" url="restaurantlist.jsp" resultFormat="xml"/> <mx:Button label="Get data" click="srv.send()"/> <mx:DataGrid id="dg" dataProvider="{srv.result.list.restaurant}" width="100%" height="100%"/> </mx:Application> The XML returned by the servlet is like: <?xml version="1.0" encoding="utf-8"?> <list> <restaurant> <name>Addis Red Sea</name> <address>544 Tremont St</address> <city>Boston</city> <zip></zip> <phone>(617) 426-8727</phone> <description>test</description> <image>addis.jpg</image> <link>http://www.addisredsea.com</link> <mapX>375.0</mapX> <mapY>291.0</mapY> <review>Addis Red Sea is one of Boston's only authentic Ethiopian restaurants. We are proud to offer traditional Ethiopian cuisine in a warm and friendly environment.</review> </restaurant> This is really confusing, dont you think ? --- In [email protected], Matt Chotin <[EMAIL PROTECTED]> wrote: > The List classes can't handle XML, they take arrays of objects.
