Estou usando vraptor 3.4.1, JSTL 1.2.1 ,Tomcat 7.0.27, e quando vou renderizar uma jsp me aparece um erro de conversão : javax.el.ELException: Cannot convert P of type class java.lang.String to class java.lang.Long , quando eu removo as partes do codigo que eu faço comparação,tudo fica normal,mas eu preciso realizar essas comparações. Talves nem seja o vraptor,mas não entendo o prq desse erro aparecer,já testei com varias versões do tomcat e o erro persiste,no glassfish esse erro não acontece mas prefiro o tomcat para desenvolvimento.
Erro que aparece no console:
