Choosing default basemap

[JamesMitchell_Jr_]

I've built a flex application using ArcGIS Viewer for Flex that uses the MapSwitcher widget to display the ESRI basemaps and a custom cached basemap I've published. Everything works well except the application wants to use my custom based map as the default. If I change the visibility of that layer to "false" it turns off the layer at startup but does not display one of the ESRI layers. What I would like to have is the ESRI Topographic Basemap to show up by default? Any ideas?

Your best bet is to add the basemaps in individually into the config.xml, that way you have total control over them, do not forget to turn the addarcgisbasemaps tag to false:

You can then add or remove base maps as you want
