3.0 Prerelease only works with 4.5 and above.

I think in your case, maybe you have not added the API Library (the SWC file) yet? You need to download it separately - http://links.esri.com/flex-api/latest-download.

See http://resourcesbeta.arcgis.com/en/h...000001q000000/ for how to include it in your project.

That's the "3.0 beta 1" SWC. Try with the "3.0 Prerelease" SWC instead: http://links.esri.com/flex-api/latest-download

Derek,

Are you talking about the Flex Viewer's MapSwitcher?... Because you are posting to the AGS Flex API forum post announcement for the 3.0 pre release API... Maybe you are looking for this documentation from the Flex Viewer 3.0 pre release:

Correct, the "units" have been removed (and it wasn't mentioned in the "prerelease" release note). This property was needed for the Map in a few edge cases where it wouldn't get the Units from the metadata of the first layer added to the map. At 3.0, the API is now figuring out the units based on the spatial reference, thus no more need for the "unit". At least that's what we were thinking...

What are you using the GraphicsLayer.units for?

Will it (at 3.0) just work fine if you remove those lines?
