Ok. Rafael, could you create an issue?

it isn't nice that we need such a workaround, however, we can add it easily

Gerhard, i would add the null check but we should do it in
AbstractContext.
Could it break anything?

Hi again,
i just solved it in my custom scope by checking the null contextual:
@Override
public T T get(final ContextualT contextual, final
CreationalContextT creationalContext) {
if(creationalContext == null){
return null;
}
i dont know what the spec says about trying to get a bean which doesnt
have to participate in an event but in my opinion the easiest way to
get
DS
compatible with GF4 is to
do that nullcheck in deltaspike instead of waiting for GF guys...

CODI issue with CDI Observer
Hi guys,
i'm facing an issue with CODI on Glassfish 4 which i can't observe CDI events
with notifyObserver = Reception.IF_EXISTS if my bean uses a CODI scope, here is
some code:
@ViewAccessScoped
@Named
public class MyBean implements Serializable{
@Inject
EventMyEvent myEvent;
public void fire(){
myEvent.fire(new MyEvent());
}
}
@ViewAccessScoped
//@SessionScoped
@Named
public class AnotherBean implements Serializable{
protected Logger log = Logger.getLogger(getClass().getSimpleName());
public void observe(@Observes(notifyObserver = Reception.IF_EXISTS) MyEvent
event){
log.fine(event received:+event);
}
i receive nullpointer exception when i fire the event:
javax.faces.FacesException: #{myBean.fire}: java.lang.NullPointerException
at
com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:118)
at
org.apache.myfaces.extensions.cdi.jsf.impl.security.SecurityViolationAwareActionListener.processAction(SecurityViolationAwareActionListener.java:56)

at
org.apache.myfaces.extensions.cdi.jsf.impl.listener.action.CodiActionListener.processAction(CodiActionListener.java:58)
full stacktrace is here:http://pastebin.com/fMaMqS72
Here is some observations:
- if i replace ViewAccessScoped with SessionScope i get no errors.
- if i remove notifyObserver = Reception.IF_EXISTS i receive the event without
problems
- I have no issue with JbossAS 7, wildfly and also Glassfish 3.1.1.2
I pushed a simple project at github which reproduces the issue:
github.com/rmpestano/codi-issue
any help is appreciated.

Re: CODI issue with CDI Observer
Hi Gerhard,
i can confirm its a GF4 issue, justed added a simple custom scope and received
the same NPE in the scope GET method:
@Override
public T T get(final ContextualT contextual, final CreationalContextT
creationalContext) {
Bean bean = (Bean) contextual;
if
(customScopeContextHolder.getBeans().containsKey(bean.getBeanClass())) {
return (T)
customScopeContextHolder.getBean(bean.getBeanClass()).instance;
} else {
T t = (T) bean.create(creationalContext);//NPE here, contextual is
null
I'll open an issue at glassfish tracker.
thanks for your help

at
org.apache.myfaces.extensions.cdi.jsf.impl.listener.action.CodiActionListener.processAction(CodiActionListener.java:58)
full stacktrace is here:http://pastebin.com/fMaMqS72
Here is some observations:
- if i replace ViewAccessScoped with SessionScope i get no errors.
- if i remove notifyObserver = Reception.IF_EXISTS i receive the event
without problems
- I have no issue with JbossAS 7, wildfly and also Glassfish 3.1.1.2
I pushed a simple project at github which reproduces the issue:
github.com/rmpestano/codi-issue
any help is appreciated.

Re: CODI issue with CDI Observer
Hi again,
i just solved it in my custom scope by checking the null contextual:
@Override
public T T get(final ContextualT contextual, final CreationalContextT
creationalContext) {
if(creationalContext == null){
return null;
}
i dont know what the spec says about trying to get a bean which doesnt have to
participate in an event but in my opinion the easiest way to get DS compatible
with GF4 is to
do that nullcheck in deltaspike instead of waiting for GF guys...

Hi Gerhard,
i can confirm its a GF4 issue, justed added a simple custom scope and received
the same NPE in the scope GET method:
@Override
public T T get(final ContextualT contextual, final CreationalContextT
creationalContext) {
Bean bean = (Bean) contextual;
if
(customScopeContextHolder.getBeans().containsKey(bean.getBeanClass())) {
return (T)
customScopeContextHolder.getBean(bean.getBeanClass()).instance;
} else {
T t = (T) bean.create(creationalContext);//NPE here, contextual is
null
I'll open an issue at glassfish tracker.
thanks for your help

Hi guys,
i'm facing an issue with CODI on Glassfish 4 which i can't observe CDI
events with notifyObserver = Reception.IF_EXISTS if my bean uses a CODI
scope, here is some code:
@ViewAccessScoped
@Named
public class MyBean implements Serializable{
@Inject
EventMyEvent myEvent;
public void fire(){
myEvent.fire(new MyEvent());
}
}
@ViewAccessScoped
//@SessionScoped
@Named
public class AnotherBean implements Serializable{
protected Logger log = Logger.getLogger(getClass().getSimpleName());
public void observe(@Observes(notifyObserver = Reception.IF_EXISTS)
MyEvent event){
log.fine(event received:+event);
}
i receive nullpointer exception when i fire the event:
javax.faces.FacesException: #{myBean.fire}:
java.lang.NullPointerException

com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:118)

Re: CODI issue with CDI Observer
Gerhard, i would add the null check but we should do it in AbstractContext.
Could it break anything?

Re: CODI issue with CDI Observer
it isn't nice that we need such a workaround, however, we can add it easily
(in codi as well as in deltaspike).
