I'm using: Wildfly 8.2, JSF 2.2 (Mojarra 2.2.8) , Omnifaces 2.1 and java 7.
The problem is that I've created some objects and every request they are recreated (null). I also tried using conversationScope but the same thing happens.
Using sessionScope it works.
Controller:
@Named
@ViewScoped
public class Teste implements Serializable {
private static final long serialVersionUID = 1L;
private Map<String, String> passwordReminderUsers;
private String key;
@PostConstruct
public void init() {
if (!FacesContext.getCurrentInstance().isPostback())
passwordReminderUsers = new HashMap<String, String>();
}
public void add() {
passwordReminderUsers.put(key, "b");
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
}
The passwordReminderUsers is null on every postback, causing NPE.
View:
<h:form id="form-login" prependId="false">
<h:inputText value="#{teste.key}" />
<h:commandButton value="add" action="#{teste.add()}" />
</h:form>
I've made some tests doing the request without primefaces, with f:ajax, and several others, nothing works.
this code: JSF view scoped bean: #{authenticator} shows that every request the bean is recreated.
Maybe related: We were using the JSF 2.0 and updated some months ago to JSF 2.2. I have to use these namespaces:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:pe="http://primefaces.org/ui/extensions"
template="/WEB-INF/templates/default.xhtml">
Because the new xmlns.jcp.org ones didn't work and started to break the pages and not render jsf components.

Maybe related: We were using the JSF 2.0 and updated some months ago to JSF 2.2. I have to use these namespaces [snip] Because the new xmlns.jcp.org ones didn't work and started to break the pages and not render jsf components
This is definitely a strong clue that you are actually not using JSF 2.2, but still an older version. If that happened while running on WildFly, which is supposed to already provide JSF 2.2 out the box, then this means that your runtime classpath is polluted with multiple different JSF versions, or that the WildFly instance is modified.
It should work fine on a stock and unmodified WildFly instance.
