How to do breadcrumbs using richfaces JSF and spring?
I tried to do implement breadcrumb application by saving the path in the bean but the problem is i am not able to bring it up that on the webpage
the layout which needs to be inserted all the pages:
<rich:spacer height = "30px"/>
<div>
<a4j:form id="breadCrumb">
<a4j:keepAlive beanName="breadCrumbBean" />
Bread Crumbs:
<rich:panel>
<ui:repeat var="link" value="#{breadCrumbBean.path}"> path is the list of strings which stores the address
<h:outputText value ="#{link}"/>
</ui:repeat>
</rich:panel>
</a4j:form>
</div>
</body>
i have used the bean as phase listener also declare this class i faces-config life cycle and also in the spring xml files
public class BreadcrumbBean implements PhaseListener
{
private static final long serialVersionUID = 1L;
private ArrayList<String> path = new ArrayList<String>();
private String currentPage = "";
private String newPage = "";
private String requestedPage ="";
private PhaseEvent event;
private String link;
private String home ="/faces/Home.faces";
public BreadcrumbBean()
{
super();
path.clear();
}
@Override
public void afterPhase(PhaseEvent e) {
if (e.getPhaseId() == PhaseId.RESTORE_VIEW) {
FacesContext context = e.getFacesContext();
HttpServletRequest request = (HttpServletRequest) context.getExternalContext().getRequest();
setLink(request.getServletPath());
// System.out.println(link);
System.out.println("after phase");
displayPath();
}
}
private void displayPath()
{
newPage=link;
if(!path.contains(link))
path.add(newPage);
for (String paths:path)
System.out.println("displaypath" + paths);
}
public void linkToThisPage() throws ServiceException
{
String link = FacesContext.getCurrentInstance().getExternalContext()
.getRequestParameterMap().get("pageLink");
for(String page : path)
{
if(page==link)
{
PhaseEvent event = getEvent();
redirect(link,event.getFacesContext());
}
}
}
//other functonality is igored for now
private void redirect(String navigation, FacesContext context){
context.getApplication().getNavigationHandler().handleNavigation(context, null, navigation);
}
@Override
public void beforePhase(PhaseEvent event)
{
System.out.println("before phase");
//if(event.getFacesContext().)
}
private void resetBreadCrumb()
{
path.clear();
path.add(currentPage);
}
@Override
public PhaseId getPhaseId()
{
return PhaseId.RESTORE_VIEW;
}
.....getters and setters
it is not working i think the bean is getting populated
