Re: Setting ViewRoot of FacesContext reloads the page _twice_
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

Matthes

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

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

[tomahawk sandbox] dynamic PPR content changes
hi all,
i've got a problem with dynamically changing the content of my page with the
PPR components of the sandbox.
i'm using myfaces-core-1.1.5, tomahawk-1.1.5 and
tomahawk-sandbox-1.1.6-SNAPSHOT.
here is my code:
-
h:form id=form1
t:commandLink id=switchToPage2 action=#{
contentIncludeBean.switchToPage2} value=switch content/
f:verbatimbr //f:verbatim
s:pprPanelGroup id=pageContent partialTriggers=switchToPage2
f:subview id=page1Content rendered=#{
contentIncludeBean.includeString == 'page1'}
f:verbatimdivpage1/div/f:verbatim
/f:subview
f:subview id=page2Content rendered=#{
contentIncludeBean.includeString == 'page2'}
f:verbatimdivpage2/div/f:verbatim
/f:subview
h:outputText value=#{contentIncludeBean.includeString ==
'page1'}/h:outputText
h:outputText value=#{contentIncludeBean.includeString ==
'page2'}/h:outputText
/s:pprPanelGroup
/h:form
-
and the bean has this method:
-
public void switchToPage2() {
includeString = page2;
}
-
when loading the page for the first time the subview page1Content is
rendered, so its working correct. then when i hit the commandLink both
subviews are not rendered but the boolean values calculated below are
correct: false / true.
is there a way to fix this problem? or is there another (perhaps better) way
to get this to work?
regards,
Matthes Rieke
Re: [tomahawk sandbox] dynamic PPR content changes
hi,
aaah ok. fixed that one. i'm kind of new to myfaces so things like this
happen to me often :-)
thanks for the help!

Hi,
you cant use f:verbatim in ppr updates.
content of verbatim is transient and not restored at rerendering.
