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:

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.

web.xml 
&lt;?xml version=&quot;1.0&quot;?&gt;
&lt;web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"&gt;
	&lt;display-name&gt;appteste&lt;/display-name&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;javax.faces.CONFIG_FILES&lt;/param-name&gt;
		&lt;param-value&gt;/WEB-INF/faces-config.xml&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;javax.faces.DEFAULT_SUFFIX&lt;/param-name&gt;
		&lt;param-value&gt;.xhtml&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;facelets.REFRESH_PERIOD&lt;/param-name&gt;
		&lt;param-value&gt;2&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;facelets.DEVELOPMENT&lt;/param-name&gt;
		&lt;param-value&gt;true&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;javax.faces.STATE_SAVING_METHOD&lt;/param-name&gt;
		&lt;param-value&gt;client&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;com.sun.faces.validateXml&lt;/param-name&gt;
		&lt;param-value&gt;true&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;com.sun.faces.verifyObjects&lt;/param-name&gt;
		&lt;param-value&gt;true&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;context-param&gt;
		&lt;param-name&gt;org.richfaces.SKIN&lt;/param-name&gt;
		&lt;param-value&gt;emeraldTown&lt;/param-value&gt;
	&lt;/context-param&gt;
	&lt;filter&gt;
		&lt;display-name&gt;RichFaces Filter&lt;/display-name&gt;
		&lt;filter-name&gt;richfaces&lt;/filter-name&gt;
		&lt;filter-class&gt;org.ajax4jsf.Filter&lt;/filter-class&gt;
	&lt;/filter&gt;
	&lt;filter-mapping&gt;
		&lt;filter-name&gt;richfaces&lt;/filter-name&gt;
		&lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt;
		&lt;dispatcher&gt;REQUEST&lt;/dispatcher&gt;
		&lt;dispatcher&gt;FORWARD&lt;/dispatcher&gt;
		&lt;dispatcher&gt;INCLUDE&lt;/dispatcher&gt;
	&lt;/filter-mapping&gt;
	&lt;listener&gt;
		&lt;listener-class&gt;
			com.sun.faces.config.ConfigureListener
		&lt;/listener-class&gt;
	&lt;/listener&gt;
	&lt;servlet&gt;
		&lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt;
		&lt;servlet-class&gt;javax.faces.webapp.FacesServlet&lt;/servlet-class&gt;
		&lt;load-on-startup&gt;1&lt;/load-on-startup&gt;
	&lt;/servlet&gt;
	&lt;servlet-mapping&gt;
		&lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt;
		&lt;url-pattern&gt;*.jsf&lt;/url-pattern&gt;
	&lt;/servlet-mapping&gt;
        &lt;servlet-mapping&gt;
		&lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt;
		&lt;url-pattern&gt;*.xhtml&lt;/url-pattern&gt;
	&lt;/servlet-mapping&gt;

	&lt;login-config&gt;
		&lt;auth-method&gt;BASIC&lt;/auth-method&gt;
	&lt;/login-config&gt;
&lt;/web-app&gt;

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

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.
