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?

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
I'm trying to figure out how to open a dialog box when an element in a pie chart is clicked. I'm new to Primefaces, so most of what I've found in searches are more complex examples than what I'm trying to accomplish. The dialog box is opened using the Dialog Framework. I've been able to open the dialog via a command button no problem, so I'm pretty sure the problem isn't with the dialog itself.
Here's the initial page:

}
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.

When I load any view it show the following ajax error:
Firefox:
TypeError: (intermediate value).exec(...) is null
Chrome:
Uncaught TypeError: Cannot read property '0' of null
And finally, the template.xhml file:

This happens only using fields of type java.util.Date When I have two attributes of type Date in two backing beans with the same name
It was fixed since primefaces 5.1
I have main page index.xhtml with declared place to put content dependent on page clicked.
<br>
<div id="centerContent">
<ui:insert name="centerContent" >
<ui:param name="mainTag" value="" />
<ui:include src="/template/commonContent.xhtml" />
</ui:insert>
<h4>#{mainTag}</h4>
</div>
</br><br></br>
<p:panel id="content">
<h:form>
<h:inputText id="namez" ></h:inputText>
</h:form>
</p:panel>
</p:layoutUnit>
my template commonContent is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:ui="http://java.sun.com/jsf/facelets"
>
<body>
<ui:composition>
<h1>Ubezpieczamy najlepiej!</h1>
</ui:composition>
</body>
</html>
and page for sending emails is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<h:body>
<ui:composition template="index.xhtml">
<ui:define name="centerContent">
<h2>Zapytaj</h2>
<h:commandButton actionListener="#{mySendBean.sendMail2()}" value="Welcome Me">
</h:commandButton>
<ui:param name="mainTag" value="Z chęcią odpowiemy" />
</ui:define>
</ui:composition>
</h:body>
when commandButton is put on main pages it works, email is sent, but when loaded via template it didn't work. All things work but not <h:commandButton actionListener="#{mySendBean.sendMail2()}" value="Welcome Me">. Why it doesn't work when loaded via clicked template?
