Jsf iceface 2.0：如何在icepush中保留价值？

我想将ice推送集成到我的web应用程序中

我有一个页面（placeinfo.jsf）显示一个地方的信息，ui:include weather.jsf显示该地方的天气信息

用户可以访问位于的页面

代码的简单示例，
placeinfo.jsf
1） ice:output value=“placeInfoBean.population”
2） ice:output value=“placeInfoBean.language”
3） ui:include src=“./weather.xhtml”

weather.jsf
1） 冰：输出值=“weatherBean.湿度”
2） ice:output value=“weatherBean.visibility”

PlaceInfoBean.java

@ManagedBean(name="placeInfoBean")
@RequestScoped
public class PlaceInfoBean
{
    String population;
    String language;

    @PostConstruct
    public void init()
    {
       HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
       String place = request.getParameter("place");
       setPopulation(PlaceInfoDao.getPopulation(place));
       setLanguage(PlaceInfoDao.getlanguage(place));
    }
}

@ManagedBean(name="weatherBean")
@RequestScoped
public class WeatherBean
{
    String humidity;
    String visibility;

    @PostConstruct
    public void init()
    {
       HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
       String place = request.getParameter("place");
       setHumidity(WeatherDao.getHumidity(place));
       setVisibility(WeatherDao.getVisibility(place));
    }

    public WeatherBean()
    {
        PushRenderer.addCurrentSession("weather");
    }
}

WeatherBean.java

@ManagedBean(name="placeInfoBean")
@RequestScoped
public class PlaceInfoBean
{
    String population;
    String language;

    @PostConstruct
    public void init()
    {
       HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
       String place = request.getParameter("place");
       setPopulation(PlaceInfoDao.getPopulation(place));
       setLanguage(PlaceInfoDao.getlanguage(place));
    }
}

@ManagedBean(name="weatherBean")
@RequestScoped
public class WeatherBean
{
    String humidity;
    String visibility;

    @PostConstruct
    public void init()
    {
       HttpServletRequest request= (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
       String place = request.getParameter("place");
       setHumidity(WeatherDao.getHumidity(place));
       setVisibility(WeatherDao.getVisibility(place));
    }

    public WeatherBean()
    {
        PushRenderer.addCurrentSession("weather");
    }
}

我有另一个页面来更新天气，该方法调用
PushRenderer.render（“天气”）
WeatherBean实际上重新运行了一个refresh，postconstrust方法，但发现没有假定为“california”的“place”请求参数，并且页面无法正常工作。

问题：
1） 除了会话之外，页面在执行操作之前如何记住值？

2） 获取WeatherBean的请求参数是否合适？
或者请求参数应该由ui:param从placeInfo.jsf传递？
如何在WeatherBean中获取ui:param的值

谢谢大家!

您是否尝试将托管bean设置为@SessionScoped？或者@ApplicationScoped？它起作用了吗
