当我在复合表中定义 2 个 actionListener 时，第一个 actionListener 将在我单击它时被调用两次，但第二个监听器工作正常而没有问题。即使我切换了 2 个听众，第一个总是叫了两次，第二个很好。
这是xhtml：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"

xmlns:asias="http://java.sun.com/jsf/composite/components/asias"
xmlns:test="http://java.sun.com/jsf/composite/test">
<h:head />
<h:body>
<h:form id="communityMembersForm">
<test:outertable list="#{memberController.members}"
title="Nested Table Test">
<f:actionListener for="sortAction"
binding="#{memberController.sortActionListener}" />
<f:actionListener for="actions"
binding="#{memberController.actionsActionListener}" />
</test:outertable>
</h:form>
</h:body>
</html>
MemberController 是一个 viewScoped 托管 bean。外部表定义为：

这是输出：

从输出来看，第一个 actionListener 调用了两次，但第二个按预期只调用了一次。
这是使用 jsf 2.1.13 在 tomecat 6.0.36 下运行的。如果我使用 myfaces 而不是 jsf，就没有这个问题。
