I am trying to implement simple page navigation. So whenever I click on login button it should simply redirect me to welcome page and show welcome message.

this is my login bean which contains a goToWelcome method which returns string.
LoginBean.java
#SessionScoped
#ManagedBean
public class LoginBean implements Serializable{
private User user;
public LoginBean(){
}
#PostConstruct
public void init(){
user= new User();
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String goToWelcome(){
return "/pages/welcome?faces-redirect=true";
}
}
the error says:-
Unable to find matching navigation case with from-view-id
'/index.xhtml' for action '#{loginBean.goToWelcome()}' with outcome
'/pages/welcome?faces-redirect=true'
There are many ways to return a page!
The very simple one : return a page like this for example in your backingBean:
return "DesiredPage.xhtml";
That page must be in WebPages folder.

p:commandbutton action doesn't work inside p:dialog
(4 answers)
Closed 2 years ago.
I have a dialog in a form. The dialog has an inputTextarea and a commandButton. The commandButton uses actionListener to call a method on the bean. My issue is that the data in the inputTextarea is not available to my actionListener's method. The comments field shown below is null on the bean. How can I get access to it's contents in my bean's method?

Answered with this - Primefaces dialog with modal=true not working properly. In order to make a modal form, you have to use appendTo="#(body)" and if you use appendTo, you will be outside the page's form, so you have to embed a separate form (outside of the main page's form) inside your dialog

This is the controller:
#Named("registerController")
#SessionScoped
public class RegisterController implements Serializable {
#Inject
private UserManager userManager;
private User user;
private Logger logger = Logger.getLogger(RegisterController.class);
public RegisterController() {
logger.debug("Created RegisterController");
user = new User();
if(user != null)
logger.debug("Name: " + user.getName()
+"\nEmail: " + user.getEmail());
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}

+ "\n Name: " + user.getName()
+"\nEmail: " + user.getEmail());
userManager.addUser(user);
logger.debug("registerUser end");
return "benutzer.jsf";
}
}
It even is not entering the action method of my commandButton when I try to debug it (I am using the Bootsfaces Framework but I don't think this has anything to do with that Framework).
Setting the save state to client works but I would like to understand what is the problem? From what I am understanding of JSF this should work without pushing the state to the client side.
Am I missing something fundamental?
I deployed the webapp to a widlfly 9 server.
It was a bug in the used wildfly version - just used the new widlfly 10 final release and it is working as it should.

any idea ???
Please help :(
Your question is not complete, since it does not provide all the elements to reproduce the bug. You haven't provided the page that calls your element, neither the converter, etc.
JSF's debugger best friend is firebug. Always check for javascript errors and enable the network tab to see each request response body, which may contain "silent" error messages.
I'll take my risk trying to guess your problem :-)

I've noticed that if you don't omit the HEAD section from the caller page, it seems to render and work.
But if you forget the HEAD section (you must not, see Primefaces FAQ item #2), you'll render the page (quite) but you'll get some javascript errors and your page won't work. The HEAD section I am talking about is this
<h:head>
<title>You NEED a header</title>
</h:head>
This is how it looks without the HEAD section.
With the HEAD section, it seems to work. Also notice the subtle primefaces look and feel.
What should be the return type for getResponse and submit, and are both necessary?
When a guess is entered in either the firstForm or SecondForm, how do I echo that guess to the same webpage?
Either with ajax, and so not reloading the same page
or
loading a new page, guessResults.xhtml, for example, which echo's the guess.

I'm running facelets on Glassfish, using CDI, so am using #Named and not #ManagedBean -- some of the documentation above is more geared for #ManagedBean, but I'm not sure how much that matters.
The goal is one step better than "hello world", "hello world, your guess is " would be a good result. If there's a specific manual, I don't mind a RTFM to that specific documentation. The Oracle docs are probably the best for facelets?

#ViewScoped beans are alive per view. If you open a popup window from your current view, then you're opening a new view, so even if it uses the same managed bean to display the data, since they're different views, they use different instances of the same class.
In cases like this, you should pass a parameter through query string, then receive it in your view and process it to load the desired data. In this case, your code would be like this (note: make sure you send the parameter with name "urunId"):

UruneGozAtBean managed bean:
#ViewScoped
#ManagedBean
public class UruneGozAtBean {
//your current fields, getters and setters...
private Long urunId;
//getter and setter for this field...
public void loadData() {
if (urunId != null) {
//load the data for the table...
}
}
}

How to choose the right bean scope?
DataTable expects a list to iterate through, but as far as I can see you return an UrunIcerik object.
