When using

Code:
 Map {
                 id: map
                 plugin : Plugin {
                             name : "nokia"
                             }
                 size.width: parent.width
                 size.height: 200
                 zoomLevel: 20
                 center: Coordinate {
                             latitude: lat
                             longitude: lon
                         }

                 MapCircle{
                     center : Coordinate {
                                         latitude : lat
                                         longitude : lon
                                         }
                     radius : 10.0
                     color: "red"
                 }

             }
it's giving

Code:
********************************************************************************

I think I should give it in the Plugin parameters

Code:
Plugin {
                             name : "nokia"

                             parameters: {
                                 PluginParameter {
                                  name: "mapping.referer"
                                  value: "xx"
                                 },
                                 PluginParameter {
                                  name: "mapping.token"
                                  value: "yy"
                                 }
                             }
                         }
but how the parameters should be put?
