Myfaces example PanelNavigation Item toggles activ/open depending on ViewId
(with Trinidad)
-------------------------------------------------------------------------------------------
Key: TOMAHAWK-1047
URL: https://issues.apache.org/jira/browse/TOMAHAWK-1047
Project: MyFaces Tomahawk
Issue Type: Bug
Components: Panel Navigation2
Reporter: Leonardo Uribe
Attachments: patch5.patch
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.HtmlPanelNavigationMenu.restoreOpenActiveStates(HtmlPanelNavigationMenu.java:93)

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.
