如何限制在主表面应用程序的会话中存储视图的数量

Question

我们在我们的应用程序中使用了primefaces 2.2.1版本。我们想限制将存储在会话中的视图存储为3.我已经将我的web.xml配置为：

<context-param>
    <description>State saving method: 'client' or 'server' (=default).See JSF  Specification 2.5.2</description>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
</context-param>

<context-param>
    <description>The maximum number of logical views (GET requests) to store per session (http://tinyurl.com/yw6f2e)</description>
    <param-name>com.sun.faces.numberOfLogicalViews</param-name>
    <param-value>3</param-value>
</context-param>

<context-param>
    <description>The maximum number of JSF views (POST requests) stored in the session for per logical view (http://tinyurl.com/yw6f2e)</description>
    <param-name>com.sun.faces.numberOfViewsInSession</param-name>
    <param-value>3</param-value>
</context-param>

看来，这种配置不起作用。当我查看内存堆转储时，我发现在会话中存储了15个视图。

使用Primefaces 2.2.1，在Mojarra 2.0.9上运行JSF 2.0.9

任何想法......
