Setting ViewRoot of FacesContext reloads the page _twice_
Hi all,
i've got a problem with my self-written PhaseListener. It is a RESTORE_VIEW
listener and is intended to deal with pretty URLs:
e.g.:
www.server.com/webapp/user/123
the listener splits the requestURI (into an array [webapp, user, 123]). this
works fine. i then put the parameters into some beans. works fine too (i
create session-scope beans if they do not exist and put them into the
FacesContext).
Now, here is my problem. i then want to change the ViewRoot to do an
internal forward to the index.jsp (this one generates the content from the
beans):
private FacesContext context;
.
.
.
//set the viewroot to show the indexpage!
UIViewRoot view = context.getApplication().
getViewHandler().createView(context, "/jsp/index.jsp");
context.setViewRoot(view);
the index.jsp is loaded correctly, but when it is finished, it starts
loading again. weird thing about that: it does not load any css-styles, so
it is completely useless (besides its useless cos its loading twice).
anyone got an idea?
regards,
Matthes

hi again!
of course, here is my sourcecode for the Servlet:
in the servlet-class:
@Override
protected void service(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
String uri = request.getRequestURI();
LifecycleFactory lFactory = (LifecycleFactory)
FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
Lifecycle lifecycle =
lFactory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
FacesContextFactory fcFactory = (FacesContextFactory)
FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
FacesContext facesContext =
fcFactory.getFacesContext(getServletContext(), request,
response,
lifecycle);
Application application = facesContext.getApplication();
ViewHandler viewHandler = application.getViewHandler();
String viewId = "";
UIViewRoot view = viewHandler.createView(facesContext, viewId);
facesContext.setViewRoot(view);
String[] parts = uri.split("/");
if (uri != null) {
String app = parts[2];
if ("news".equals(app)) {
handleNews(parts);
} else if ("user".equals(app)) {
handleUser(parts);
} else if ("tag".equals(app)) {
handleTag(parts);
}
}
// specify what outcome value you want to use for navigation
String outcome="SUCCESS";
if (facesContext.getResponseComplete()) {
return;
}
if (log.isDebugEnabled()) {
log.debug("outcome = '" + outcome + "'");
}
NavigationHandler navigationHandler =
application.getNavigationHandler();
navigationHandler.handleNavigation(facesContext, null, outcome);
lifecycle.render(facesContext);
}
i have not specified any navigation rules for this one. one thing i noticed,
if i make a
response.sendRedirect("jsp/index.faces");
at the end of the service-method, there is no endless loop, but the URL
changes and i do not want that.
thanks and regards,
Matthes

Hi Matthes,
can you post your source?
the Servlet and the navigation rules.

hi volker,
thanks for the tip. seems to be a better solution ;-)
now, changes it into a servlet, i get another confusing problem. i have
overwritten the protected void service(...) method as described in the link
you have posted. however, now this service method is called in an infinite
loop. and from the 2nd time its called the requestURI changes. my URI looks
like this:
/webapp/group/1234
and from the second time it is just
/webapp/group
hoping for a help on this one! thanks
regards,
Matthes

Hi,
i think you should not use a PhaseListener, but a servlet.
