Erro com Sandbox do Myfaces

Front-end
#1

Bom dia…

Já estou quase desistindo aqui, tenho um projeto com o MyFaces, Tomahawk, até aí tudo bem. Mas quando jogo a lib do Sandbox, o Tomcat não inicia a minha app e me mostra o erro: [quote]SEVERE: Error listenerStart[/quote]Se tiro a lib do sandbox, inicia normalmente. Já aconteceu o mesmo com alguem?
