I am using Primefaces fileUpload component in advanced mode to upload multiple images. When i select few files and press upload button, my #ViewScoped managed bean recreates multiple times. That is a problem for me, because i want to store all files uploaded within one view interaction in separate folder, but I'm getting multiple folders - one for each file. When I made my managed bean #SessionScoped the problem is gone, also i found that this bug appears only after server restart for the first uploading, so when i reload view and upload data second time everything is ok.
I am using Tomcat 7, jsf 2.2 and prime faces 5.1
Here is jsf page:

I deploy on Wildfly 10 and i replace jsf-api and jsf-impl reading this guides:
step 1 (how to packages jars):
How to install one jar variant of JSF (javax.faces.jar) on WildFly
step 2 (how to install):
Upgrade JSF / Mojarra in JBoss AS / EAP / WildFly
thanks you

SAME ERROR IN ANOTHER QUESTION
There should be a bean.xml
and
a faces-config.xml for faces application (JSF)
Changing faces-config.xml from 2.2 to 2.3 causes javax.el.PropertyNotFoundException: Target Unreachable, identifier 'bean' resolved to null
ALSO
Of the error and the property value being null.
check the bean "state" configuration session or page... (should be session)
if it not session then it will be dropped each time a request is made.
It is a mapping to the bean class gone wrong for the error
javax.el.PropertyNotFoundException: /mail.xhtml #14,72 value="#{emailBean.email}": Target Unreachable, identifier 'emailBean' resolved to null
==== old info -
I believe your faces navigation rules for JSF configuration from and to a page should have names and should be clarified in your web.xml
Here is a link to "simple" a tutorial page for a J2EE server for JSF to explain.
http://tomee.apache.org/examples-trunk/jsf-managedBean-and-ejb/README.html
(note careful of the call syntax in the code too)
This question already has answers here:
How to use PrimeFaces p:fileUpload? Listener method is never invoked or UploadedFile is null / throws an error / not usable
(11 answers)
Closed 5 years ago.
I'm trying to implement a FileUpload feature in a simple JSF/CDI project, with correct dependencies(i think) and the same code that i found in the primefaces showcase.
But for some reason, the FileUpload event does not found the listener in my ManagedBean.
I hope i can see something that i'm missing here, i already inspected the code a lot of times but i dont find anything that could be causing the problem.
My Xhtml page:
<html>
<h:head>
</h:head>
<body>
<h:form>
<p:fileUpload fileUploadListener="#{file.uploadHandler()}"
mode="advanced" dragDropSupport="false" update="messages"
sizeLimit="100000" fileLimit="3"
allowTypes="/(\.|\/)(gif|jpe?g|txt)$/" />
<p:growl id="messages" showDetail="true" />
</h:form>
</body>
</html>
My ManagedBean:
import javax.faces.view.ViewScoped;
import javax.inject.Named;
import org.primefaces.event.FileUploadEvent;
#Named
#ViewScoped
public class File implements Serializable {
private static final long serialVersionUID = -6644472075906217176L;
private String fileName;
public String getFileName() {

}
public void setFileName(String fileName) {
this.fileName = fileName;
}
public void uploadHandler(FileUploadEvent event) {
System.out.println("Nome do Arquivo: " + event.getFile().getFileName());
}

I have problems using h:inputFile to upload Files in JSF 2.2.7 and Glassfish 4.1. I'm trying to get h:inputFile to work, but whenever I use the uploaded Part object from h:inputFile, the Backing bean gets destroyed and created again. Also the setter for the Part object is never called. I tried to isolate the problem by creating a page just with the upload (copied from a jsf example project), but the problem is still there. I also tried to use the Primefaces p:fileUpload, but the problem was still there. I also couldn't find any solutions by googling. Thanks for the help.

I think I should see a message in the output from MailEndpoint but, I only get the message from MailObserver.pushMessage. Any ideas on what is going on?
I found the problem. I changed the wrong web.xml. To make it work, you need to add this to web.xml
<servlet>
<servlet-name>Push Servlet</servlet-name>
<servlet-class>org.primefaces.push.PushServlet</servlet-class>
<load-on-startup>1</load-on-startup>

I have a simple JSF project where I use <f:viewaction action="#{backingBean.init}"/> and the backing bean is being constructed twice. I trace out the session id and I get different session ids for each call.

I have tried other methods of calling the init() like using the #PostConstruct annotation or <f:event type="prerenderview" listener="#{backingBean.init}"/> but I get the same results. The init method is always called twice the first time when I access the page. On subsequent calls it is only called once.
