两个radio分别控制一块区域,radio A控制的区域里包含了一个selectManyListbox,也就是多选列表,希望点radio B的时候可以局部刷新selectManyListbox内的值,开始的时候百般不行,后来上网翻了下,终于解决了，这里做个记录,
先看xhtml代码<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:s="http://jboss.com/products/seam/taglib" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:rich="http://richfaces.org/rich" xmlns:a="http://richfaces.org/a4j" template="layout/template.xhtml">
