Question

我是Primefaces JSF的新手，我有三个名为Template页面的页面，带有对话框选项的主页面和带有对话框选项的bean，但是当我在对话框中单击命令按钮时，bean方法没有调用。如果有人知道这个问题，请帮助我们。感谢

Answer 1

我有同样的问题；但就我而言，那是我将素数从5.0迁移到6.2的时候。

我解决了它，删除了 或使用包装

如以下示例。

<f:facet name="footer"> <h:panelGrid columns="1" > <p:commandButton partialSubmit="true" action="#{lbc.login}" value="add"> </p:commandButton> </h:panelGrid> </f:facet>
