PrimeFaces commandButton actionListener未触发
问题描述：
我在将actionListener放入<p:commandButton>时无法在对话框中触发.我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，但到目前为止没有任何帮助.一切正常，直到我更新了Netbeans，一切都崩溃了，以某种方式删除了一个库，这是commons-fileupload jar.
I am having trouble getting my actionListener in a <p:commandButton> to fire inside of a dialog. I've tried changing it to action, removing the (), adding the (), changing the scope of the managed bean, moving around the ajax statements and nothing has helped so far. Everything worked until I updated Netbeans, everything broke, somehow a library was removed, it was the commons-fileupload jar.
仅在netbeans更新之后，才对代码进行了更改，这没有发生. Netbeans 7.3，JSF2.2，Tomcat 7，jdk1.7，primefaces 4.0.在我的tomcat管理器应用程序中，有一个工作版本，如果我可以检索到希望一切恢复正常，但是我找不到从tomcat取回文件的任何信息.所以我的问题是，为什么不触发?按钮中的通话顺序吗?我无法确定为什么这行不通.
This happened with no changes to the code, only after netbeans updated. Netbeans 7.3, JSF2.2, Tomcat 7, jdk1.7, primefaces 4.0. There is a working version of this inside of my tomcat manager application, if I could possibly retrieve that hopefully everything would be back in working order but I can't find anything about getting the files back from tomcat. So my question is, why is this not firing? Is it the order of my calls in the button? I can't wrap my head around why this is not working.
编辑错误我在切换窗体和对话框位置后收到-

答
问题出在您的对话框中. p:commandButton包含以下内容:
The problem resides in your dialog. There's p:commandButton that contains the following:
<p:commandButton update=":mainForm:DTsamplesVw" process="innerSearch"
icon="ui-icon-search" value="Search"
actionListener="#{sampleExportController.loadSearch}"
oncomplete="searchDialog.hide()"/>`
应为update=":mainForm:DTsamples"，因为您需要引用ID而不是widgetVar.祝你有美好的一天！
It should be update=":mainForm:DTsamples" since you need to reference the id and not the widgetVar. Have a nice day!
