richfaces中facelet版本升级到2时的典型错误和解决办法
<faces-config version="2.0" 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-facesconfig_2_0.xsd">
</faces-config>?
然后修改web.xml： 确认包含以下配置
<context-param>
??? <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
??? <param-value>com.sun.facelets.FaceletViewHandler</param-value>
</context-param>
