VRaptor 3.4.1 - Ognl - Malformed OGNL expression

bglbruno · Junho 4, 2013, 5:23pm

Olá pessoal. Estou usando o VRaptor 3.4.1 e uso o Ognl, e faço exclussão do iogi, que foi uma recomendação do Lucas Cavalcanti no começo do meu desenvolvimento por alguns motivos.
Durante todo o desenv tudo funcionou muito bem, eu estava com problemas e essa substituição o resolveu.
O problema é que agora, depois de muito tempo, e estou recebendo essa exception, e não tenho ideia do que possa ser.

    // e segue um erro gigante

		&lt;/dependency&gt;

		&lt;dependency&gt;
			&lt;groupId&gt;ognl&lt;/groupId&gt;

			&lt;version&gt;3.0.6&lt;/version&gt;
		&lt;/dependency&gt;

		&lt;!--  Outras dependencias  --&gt;

Tive que fazer essa substituição porque precisava trazer listas aninhadas do html.
Mas quando eu volto a usar só o iogi, ele dá erro em outro lugar, e agora se uso o ognl, dá esse problema…

Alguém sabe me ajudar nessa?

Valeu galera, forte abraço!

Isso é só debug… pode ignorar… acontece quando existem parametros na requisição que o ognl não sabe tratar.

ou está estourando uma exceção mesmo?

Acabei esquecendo de postar a Exception, desculpe Lucas.
Segue o stacktrace todo

Lucas, e essa exception está sendo lançada em vários lugares do sistema.
Acredito que seja quando acesso uma view que tenha parâmetros na url, ou coisa do tipo.

bglbruno · Junho 5, 2013, 11:02am

Eu tenho minhas implementações das classes PathAnnotationRoutesParser e DefaultPathResolver.
Será que pode ser algum problema com elas?

Uso essas minhas implementações desde o começo do projeto. Penso que talvez possa ser algo com essa versão do VRaptor, pois antes eu usava o 3.4.0.
Mas já tentei fazer downgrade da versão, e o erro ainda persiste…

Lucas_Cavalcanti · Junho 5, 2013, 1:13pm

se você sobe o nível do log pra debug ou info ao invés de trace, a exception ainda assim aparece?

bglbruno · Junho 5, 2013, 1:33pm

Resolvido.

Era isso mesmo Lucas. Putz.
Muito obrigado!

Forte abraço.
