使用视图范围 bean 时，为什么 ICEfaces 在页面卸载时发送 dispose-window 请求？

在我们的应用程序中，ICEfaces 总是在导航到另一个 JSF 页面之前发送一个 dispose-window 请求。据我所知，当将 org.icefaces.lazyWindowScope 设置为 true 并且当前请求中不涉及窗口范围的 bean 时，这种情况不应该发生。但它发生在每个链接上，并使我们的 UI 响应速度降低。但我们的应用程序中没有任何窗口范围的 bean。

使用视图范围的 bean 时发送处理请求是icefaces中的一个错误吗？可以禁用吗？ ViewScope 是在 JSF 中定义的，而不是在 ICEfaces 中定义的，我猜它应该可以在没有此处理请求的情况下工作...

@ManagedBean(name="viewScopeBean")
@ViewScoped
public class ViewScopeBean {
    public void doSomething(){
        //
    }
}

这里是示例 jsf：

<ice:form>
     <ice:commandButton value="doSomething" action="#{viewScopeBean.doSomething}"/>
     <h:link outcome="index" value="Link to same page"/>
</ice:form>

要重现，请使用上面的代码执行以下操作：

打开 firebug 的 net 选项卡并激活持久选项
，单击 doSomething-Button
单击“链接到同一页面”
=> dispose-window 将在导航之前发送

Dispose 请求参数：

ice.submit.type=ice.dispose.windowice.window

原文

in our application ICEfaces always sends a dispose-window request just before navigating to another JSF Page. as much as i understand this should not happen when having org.icefaces.lazyWindowScope set to true and there is no window-scoped bean involved in current request. but it happens on each link and makes our UI less responsive. but we don't have any window-scoped bean in our application.

is that a bug in icefaces that the dispose request is sent when using view-scoped beans? Is it possible to disable? ViewScope is defined in JSF not in ICEfaces, it should work without this dispose request i guess...

@ManagedBean(name="viewScopeBean")
@ViewScoped
public class ViewScopeBean {
    public void doSomething(){
        //
    }
}

And here the example jsf:

<ice:form>
     <ice:commandButton value="doSomething" action="#{viewScopeBean.doSomething}"/>
     <h:link outcome="index" value="Link to same page"/>
</ice:form>

To reproduce do the following using the code above:
