PrettyFaces 和 JSF ui:include 导致操作方法被调用两次

我有一个通过 beautifulfaces 请求呈现的 xhtml 视图。我遇到了一个问题，来自 beautifulfaces 的操作映射被执行两次，但仅当我有 ui:include 标签时。示例漂亮的配置如下：

 <url-mapping id="testRedirector">
      <pattern value="/project/#{lookupBean.projectId}/#{lookupBean.cardNumber}" />
      <view-id value="/lookup.xhtml" />
      <action>#{myController.init}</action>
 </url-mapping>

.xhtml 如下：

... 

<ui:include src="/header.xhtml">
    <ui:param name="this_tab_class" value="current"/>
</ui:include>

<h:panelGrid columns="4">
...

根据对 URL 的请求，我看到 myController.init() 上的日志调用被执行了两次。如果我注释掉 ui:include，则 init 只会正确调用一次。我已经在 beautifulfaces url 映射元素上尝试了其他 jsf 阶段侦听器，但所有其他枚举类型都会导致 init() 永远不会被调用。

我的问题是，如何实现将预定义的 header.xhtml 或其他预定义组件包含到页面中而不调用 RENDER_REDRAW 阶段两次的相同目标？或者这是一个漂亮面孔特有的问题？

I have an xhtml view being rendered via a prettyfaces request. I am running into a problem where the Action mapping from prettyfaces is being executed twice, but only when I have a ui:include tag. The example pretty config is like this:

 <url-mapping id="testRedirector">
      <pattern value="/project/#{lookupBean.projectId}/#{lookupBean.cardNumber}" />
      <view-id value="/lookup.xhtml" />
      <action>#{myController.init}</action>
 </url-mapping>

The .xhtml is like this:

... 

<ui:include src="/header.xhtml">
    <ui:param name="this_tab_class" value="current"/>
</ui:include>

<h:panelGrid columns="4">
...

And upon request to the URL, I see a log call on the myController.init() being executed twice. If I comment out the ui:include, the init is properly only called once. I've experimented wiht the other jsf phase listeners on prettyfaces url-mapping element, but all other enum types result in init() never being called.

My question is, how do I accomplish the same goal of including a predefined header.xhtml, or other predefined component, into a page and not invoke RENDER_REDRAW phase twice? Or is this a pretty-faces specific problem?
