但我现在有一个例外：例外情况

javax.servlet.ServletException:JBAS011048:无法构造组件实例

javax.faces.webapp.FacesServlet.service（FacesServlet.java:606）

您有两个

p:layout

？每个

p:layoutUnit

都应该在一个整体中

p:layout

。考虑到您可以将

p:layout

嵌套在

p:layoutUnit

中以制作更复杂的布局（当然，每个

p:layout

都有一个
p:layoutUnit position=“center”
：

... ... ... ...

请记住，如果您对整个页面使用p:layout，则最好使用
p:layout fullPage=“true”
.Cheers！
p:layoutUnit
必须嵌套在
p:layout
中，您有两个布局单元：西部和中部。将它们包括在
p:layout
中，但我现在遇到了这个异常：异常javax.servlet.ServletException:JBAS011048:无法构造组件实例javax.faces.webapp.FacesServlet.service（FacesServlet.java:606）！！
