我无法让actionListener中的<p:commandButton>在对话框内触发。我已经尝试将其更改为操作，删除()，添加()，更改托管bean的范围，移动ajax语句，到目前为止没有任何帮助。一切顺利，直到我更新Netbeans，一切都坏了，不知何故一个库被删除，它是commons-fileupload jar。
只有在netbeans更新后才会对代码进行任何更改。 Netbeans 7.3，JSF2.2，Tomcat 7，jdk1.7，primefaces 4.0。我的tomcat管理器应用程序内部有一个工作版本，如果我可以检索，希望一切都恢复正常工作，但我找不到任何关于从tomcat恢复文件的事情。所以我的问题是，为什么这不解雇？它是按钮中我的通话顺序吗？我无法理解为什么这不起作用。

答案 0 :(得分：5)
问题出在您的对话框中。其中p:commandButton包含以下内容：
<p:commandButton update=":mainForm:DTsamplesVw" process="innerSearch"
icon="ui-icon-search" value="Search"
actionListener="#{sampleExportController.loadSearch}"
oncomplete="searchDialog.hide()"/>`
它应该是update=":mainForm:DTsamples"，因为您需要引用id而不是widgetVar。祝你有愉快的一天！
