I'm trying to do SIMPLE webapp which show partyguest list and allow me to add new guest. I want to store guests in ArrayList. I don't know where and how to invoke party.addGuest() method.

If you are using JSF 2, you can have something like this in your index.xhtml (but it can be easily converted to earlier JSF version):
...
<h:form>
<h:inputText id="guestName" value="#{party.newGuest}"/>
<h:commandButton value="Add guest" action="#{party.addGuest()}" />
</h:form>
...
And, in Party.java:
private String newGuest;
....
public String getNewGuest() {
return this.newGuest;
}
public void setNewGuest(String guest) {
this.newGuest = guest;
}
....
public void addGuest() {
guests.add(newGuest);
newGuest = null;
}
No need for Guest.java in this use case. Could be done in a nicer way, though.

I have a primefaces datatable where the commandButton's action addItem within the columns header facet always fires the CDI #ViewScoped beans #PostConstruct method, while the commandButton's action editItem from the column does not?!
Curiously enough this happens only, if the action methods return a non-null string?! Means, if both methods return null, the #PostConstruct method is not called, but I use a non-null string, because clicking the buttons should show a new #ViewScoped page.
The main problem in my real application is, that I do some initialization stuff within #PostConstruct, which should really happen only once during page construction!

Is this a bug regarding command button within datatable column header facet? Or is there a better way, to do what I want?
I am using primefaces 6.0 on wildfly-10.0.0.Final with Mojarra 2.2.12!
Update: removed logger; call same method for addItem / editItem; added redirect / forward pages

Functionality:
Here we are navigating from index.xhtml to "register" flow scope, containing register.xhtml, register-flow.xml, confirmation.xhtml
From register.xhtml we navigate to confirmation.xhtml.
Issues:
1) I want to make a "back" output link in confirmation.xhtml to navigate back to register.xhtml
<h:outputLink value="register.xhtml">
<h:outputText value="back"></h:outputText>
</h:outputLink>
But this is not working, its giving following error when I click on "back" on UI
"WELD-001303: No active contexts for scope type javax.faces.flow.FlowScoped"
Interesting thing is <h:commandButton> is working instead.
2) Why can't we directly run a file in directory ("register").
Its giving following error:
WELD-001303: No active contexts for scope type javax.faces.flow.FlowScoped
I am confused. Please help me?
in my JSF2 app I have screens composed with :
Header
Body
In the header I have a combo list. At each change in value in the combo list I have an Ajax request that updates the data in the Body. So far everything is working properly. Now the home screen's structure should be change when the value of combo list change. To do this I have :
1 ManagedBean HomeBean that manage the home
1 ManagedBean HeaderBean that manage the header
2 object HomeScreen1.java and HomeScreen2.java that allows me to valued data from each screen
2 services HomeScreen1Loader.java and HomeScreen2Loader.java that manage loading of each type of screen
1 template home.xhtml
2 fichier home1.xhtml et home2.xhtml
When I log in to the application, I get the good page corresponding (Element type 1 => home page 1). But when I select a type 2 item, the actionListener methode is execute, ManagedBean's data was updated (for type 2 screen) , but the page does not updated. What do you do ?

I found the solution, the problem came to the ManagedBean ContextBean's templateHomeName attribute that was not properly valued. I added in loader.load(homeScreen1) and refresh and everything it's ok. I should upgrade my JSF version : 2.1.0-b11 to 2.1.26 because I had an error when refresh.
I have been trying to print the values from an ArrayList<String> in JSF Facelets, but with no luck. The value is getting stored in an ArrayList but the output is blank on the page.

private ArrayList<String> list = new ArrayList<String>();
private String companyName;
public String getCompanyName() {
return companyName;
}
public void setCompanyName(String companyName) {
this.companyName = companyName;
list.add(companyName);
System.out.println("Size of array list is : "+list.size());
for (String number : list) {
System.out.println("Number = " + number);

Instead of
<ui:repeat var="item" value="#{CompanyNames.list}"> <h1>#{item}</h1> </ui:repeat>
use
<ui:repeat var="item" value="#{newCompanyName.list}"> <h1>#{item}</h1> </ui:repeat>
You will also need a getList method for the class CompanyNames
public List<String> getList() {
return this.list;
}
Use companyNames.list instead of CompanyNames.list and you will also need the get() function of list.
I am using facelets in my views with JSF 2.0. I have two backing beans, two xhtml view files and another xhtml template file.

These are the view files:
default.xhtml

inventory.xhtml:

What is happening?
A HTTP 404 error simply means "Page Not Found". And indeed, files inside /WEB-INF folder are not publicly accessible. Put files which are intented to be publicly accessible outside /WEB-INF folder.
Note that this has further completely nothing to do with internationalization. You'd have had exactly the same problem when not doing anything with regard to internationalization (e.g. a simple navigation).
