                                       itemRenderer="com.ci.wmc.manageappliances.renderers.GridCloumnItemrender>

GridCloumnItemrenderer.as has following:

Popups.getInstance().launch(DisplayObject(parentDocument),

                        Popups.StManageAppliancesCreateCloneConfig);

Popups.as has

instance.map[StManageAppliancesCreateCloneConfig] =CreateCloneConfig;

CreateCloneConfig.as has

    new ManageCloneConfigEvent(

                    hostname,

                    vo.nodeProject,
