Starting Thursday, December 13, 2012, all my Flex Viewer 3.0 web maps that utilize the addarcgisbasemaps="true" function receive the error:
"Imagery with Labels layer failed to load: Fault code: 400
Fault info: Unable to complete operation.
Fault details: Service 'World_Imagery' of type 'MapServer' does not exist or is inaccessible."
Although the web map will still work if you 'x' out of the error screen, it still causes people to call and ask why their map is not working. Not good from the IT point of view.
Is anyone else experiencing this?
