(Help) JSF + Facelets = Erro no submit

[felipempantoja]

Olá pessoal, estou com um problema ao trabalhar com facelets, pois usando somente JSF tudo funciona normal.
Montei aqui uma aplicação de teste, onde eu tenho dois campos com nomes, e é feita uma comparação entre eles, se for igual, vai pra página “sucesso.xhtml” e se for diferente vai pra “erro.xhtml”, porém, quando eu dou o submit no form, dá erro:

alguém pode me ajudar a resolver esse problema?

[felipempantoja]

Pessoal, eu não comentei mas tb tinha os jars do richfaces no meu classpath, agora testando, removi eles e as declarações no web.xml, funcionou na boa agora, o problema é que quero integrar o richfaces na aplicação e não estou entendendo o porque do erro.

Será que tem algo errado no meu web.xml? =/

[felipempantoja]

Removi o context param do web.xml:

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>

e funcionou, mas sinceramente não sei pra que serve isso, já que o jboss tools que gerou isso pra mim.
