PanelNavigation2 and workaround and serialization

[Carsten Stiller]

Hi,

I'm trying to solve the problem with PanelNavigation2 and redirects (the 
active elements can't be saved when using redirects so the menutree 
doesn't stay open after invoking one action.)

I put a bean called menu into the weblayer where I can save the current 
HtmlNavigationMenu-item. Pretty simple, something like this:

    private HtmlPanelNavigationMenu navPanel;

    public HtmlPanelNavigationMenu getNavPanel() {
        return navPanel;
    }

    public void setNavPanel(HtmlPanelNavigationMenu navPanel) {
        this.navPanel = navPanel;
    }


and in the jsp I just use the binding-attribute of panelNavigation2:

<t:panelNavigation2 id="nav2" layout="list"  binding="#{menu.navPanel}">
    [static-commandNavigation2-Tree]
</t:panelNavigation2>


It works pretty well, but I'm getting a NotSerializableException for the 
HtmlNavigationMenu class everytime the jsp is called. The exception can 
be catched and it works anyhow ...

Is there any reason the Serializable-interface isn't implemented for 
this class?
