RichFaces rich：panel标头未出现

Question

我指定了这个

    <rich:panel>
        <f:facet name="header">
                Panel #1. Changing Style Synchronously
        </f:facet>
            Each component in the RichFaces has a pre-defined set of classes you can manipulate with. If defined, those
            classes overwrite the ones come from the skin.
    </rich:panel>

从RichFaces演示中，在我的JSF页面中，没有标题出现，尽管我的CSS中没有任何东西会干扰。 这可能是什么原因？

谢谢

Answer 1

我看不到使用f：facet有任何问题

Answer 2

尝试

<f:facet name="header">
     <div><h:graphicImage value="/images/search.png" />
     <h:outputText value=" Action Logs Search" /></div>
    </f:facet>

为了重新产生您提到的错误

Answer 3

当我不小心将面板的小平面包括在面板表单中时，我的消失了。 构面必须是模式面板的子代：

<rich:panel>
   <a4j:form> <!-- This is trouble! -->
     <f:facet name="header">
            Panel #1. Changing Style Synchronously
     </f:facet>
        Each component in the RichFaces has a pre-defined set of classes you can manipulate with. If defined, those
        classes overwrite the ones come from the skin.
   </a4j:form>
</rich:panel>

Answer 4

OK，请随时评论为什么f：facet标签不起作用，但是在更改代码时会得到漂亮的闪亮标头，因此如下所示：

<rich:panel header="header">
            Each component in the RichFaces has a pre-defined set of classes you can manipulate with. If defined, those
            classes overwrite the ones come from the skin.
    </rich:panel>
