<operationallayers> <layer label="test" type="dynamic" visible="true" url="http://myserver/arcgis/rest/services/myservice_wgs84wm/MapServer/" /> </operationallayers>
Could this be a crossdomain.xml issue? I had the same issue when setting up my flex map. The operational layers code was written correctly, but I was still unable to view the REST service in my flex app. After I placed a copy of the crossdomain.xml file in the inetpub-->wwwroot directory of the server running ArcServer, my app worked properly. Good luck!
