I don't know why happen these error

HI, I have learned about API for Flex3.0 to ready project.

I'm using flex builder version 4.1 and API Flex for 3.0

(in fact, I downloaded Flexbuilder ver. 4.0. but I know it is version 4.1 after install my PC)

I'm training output map (sample : http://resources.arcgis.com/en/help/flex-api/samples/index.html#/Tiled_Map/01nq00000058000000/

)

but,

there are 9 errors.

(I'm already import these constants, but these problems are not solved. )

close all the opened tabs, the projects then close flash builder.
after start flash builder again and open the desired project then clean all the projects (project --> clean --> clean all projects).

it sounds weird but sometimes it helps!

You'll need to use Flex SDK 4.6.
