-------------------------------------
Status: Patch Available (was: Open)

> Key: TOMAHAWK-1047

> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: Panel Navigation2

> When you mix tomahawk and trinidad, and you use <t:panelNavigation2> with
> Item toggles activ/open depending on ViewId (like in the example in myfaces-simple-example)
> throws the following error:
> 2007-07-04 20:19:29,790 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/myfaces-skins].[jsp]] Servlet.service() for servlet jsp threw exception
> java.lang.ClassCastException: org.apache.myfaces.component.html.ext.HtmlOutputText cannot be cast to org.apache.myfaces.custom.navmenu.htmlnavmenu.HtmlCommandNavigationItem
> at org.apache.myfaces.custom.navmenu.htmlnavmenu.HtmlPanelNavigationMenu.restoreOpenActiveStates(HtmlPanelNavigationMenu.java:93)
> at org.apache.myfaces.custom.navmenu.htmlnavmenu.HtmlPanelNavigationMenu.restoreOpenActiveStates(HtmlPanelNavigationMenu.java:105)
> at org.apache.myfaces.custom.navmenu.htmlnavmenu.HtmlPanelNavigationMenu.encodeBegin(HtmlPanelNavigationMenu.java:71)
> at javax.faces.webapp.UIComponentTag.encodeBegin(UIComponentTag.java:467)
> The solution that I have probed is this:
> Class HtmlPanelNavigationMenu
> public void restoreOpenActiveStates(FacesContext facesContext,
> UIViewRoot previousRoot,
> List children)
> {
> for (Iterator it = children.iterator(); it.hasNext(); )
> {
> UIComponent child = (UIComponent)it.next();
> if (child instanceof HtmlCommandNavigationItem)
> {
> HtmlCommandNavigationItem previousItem = (HtmlCommandNavigationItem)previousRoot.findComponent(child.getClientId(facesContext));
> The last line get the same component instance as child.
> I have replace the last line with this:
> HtmlCommandNavigationItem previousItem = null;
>
> try {
> previousItem = (HtmlCommandNavigationItem)previousRoot.findComponent(child.getClientId(facesContext));
> }catch (ClassCastException ex){
> previousItem = (HtmlCommandNavigationItem) child;
> }
>
> Works the same, but in case of error, cast directly.
