查看：组件中找不到* .xhtml

Question

我有一个popup log.xhtml，用于轮询服务器以显示文件的内容，并与一个名为logTailer的组件进行交互。

以下消息每2秒写入日志：

INFO: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(WARN 1), summary=(View: log.xhtml not found in component), detail=(View: log.xhtml not found in component)]

我想我可以添加<h:messages>来显示实际错误，但为什么会这样？

代码：

<script type="text/javascript">
    function scrollToBottom(elemId) {
        var textarea = document.getElementById(elemId);
        textarea.scrollTop = textarea.scrollHeight;
    }
</script>

涉及很多facelets模板。这是具有打开弹出窗口的链接的那个。这是因为我应该在同一个视图中有两个模板吗？
