In the example (http://help.arcgis.com/en/webapps/flexviewer/live/index.html?config=config-all.xml), there are several widgets under geoprocessing folder I found interesting, such as viewshed and surface profile. I'd like to incorporate these widgets in my flex viewer. But I can't find the SWFs or source code in the flex viewer download. Are these widgets included in the download?
