Why does ICEfaces send dispose-window request on page unload when using view-scoped bean?

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:

  1. open firebug's net tab and activate persist option
  2. click doSomething-Button
  3. click "link to same page"
  4. => dispose-window will be send before navigation
