[Resolvido] efeito CubeRotate no flex4

Olá pessoal tubem com você? Eu espero que sim............ por que eu estou enrolado pra caramba.

Tem um script que funcionava perfeito no flex 3 mais estou migrando para o flex 4 e esta dando erro no <mxeffects:CubeRotate>

tipo do erro é -> Could not resolve <mxeffects:CubeRotate> to a component implementation.
