look at this http://flashcongress.cn/devnet/flex/articles/migrating-flex-apps-part3.html

please check this

"Flex Build Path" -> "Library Path" -> "Component set:" to "Spark only"

if your settings is as above then change them to

"Flex Build Path" -> "Library Path" -> "Component set:" to "MX + Spark"

this will solve the problem
