Olá, estou com um erro que está acontecendo apenas em alguns métodos. Por exemplo nesse método:

Está me gerando o seguinte erro, como se já tivesse uma página default pra ir e eu estou definindo outra. (Se eu tiro o result.forwarTo() vai para uma página em branco)

Pelo pouco que li, seu problema esta em uma Expression Lenguage... algo como

${teste.metodo}

onde a variávle teste não tem o método indicado...

Verdade tinha uma variável que vinha de um outro método e nesse método que estava usando agora estava indo null. No VRaptor2 isso funcionava.
Valeu pela ajuda, o jsp seria a última coisa que eu ía olhar.

de qqer forma vc deve estar com um jstl.jar e/ou um standart.jar no seu WEB-INF/lib... tente tirá-los
