我想在用户在第一个selecOneMenu上触发事件时生成第二个selecOneMenu内容，但它不起作用。PrimeFaces p：ajax event =“change”not fired
这里是面对-config.xml中的导航规则
<navigation-rule>
<from-view-id>/index.xhtml</from-view-id>
<navigation-case>
<from-action>#{contact_.inscription_fournisseur}</from-action>
<from-outcome>success</from-outcome>
<to-view-id>xhtml/Inscription_user.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
这里是我的索引页：whene我对点击S'inscrire它启动第一个列表，重定向我Inscription_user.xhtml

有一个解决方案通过去除方法inscription_fournisseur（）在contact_ bean类方向列表中的初始化，并使它在organisation_bean类的默认构造函数中，在这种情况下它可以工作，但我不喜欢这个解决方案，我更喜欢第一种情况，请帮助我。使用了错误的命名空间<f:ajax>
我看不到任何地方的'
没有它出现在我的代码中（只是为了不发布很多代码行） – solarie 2013-04-29 16:09:37
这是整个难题中非常重要的一部分，它的缺席或存在对最终的解决方案意味着很多。你有多个，他们是嵌套？ – kolossus 2013-04-29 16:11:36
