我有一个应用程序，它的布局带有左侧和中心布局单元（demoLayout.xhtml）。在主页 (main.xhtml) 上，我在左侧布局单元 (demoTree.xhtml) 上有 p:tree，在中心布局单元 (first.xhtml、second.xhtml、third.xhtml) 上有三种不同的形式。中心表单使用树节点单击进行切换。我的默认中心表单是 first.xhtml 并且当我没有将 p:commandButton 放在 first.xhtml 上时 second.xhtml 上的命令按钮和 third.xhtml 上的操作没有被调用。当我将 p:commandButton 放在 first.xhtml 上时，其他命令按钮可以工作，但我不想将 p:commandButton 放在 first.xhtml 上。我能怎么做？
