Tried to remove the EntityManager, but none was set.

[Luiz Ricardo Vicente Rita]

Estou usando uma classe que estende Action<T> nela faço uma consulta para verificar a autenticidade do usuário que tenta acessar a aplicação,

com isso é disparado o erro abaixo no return da classe dentro do delegate.call(context).

Alguém pode me ajudar?
