hi ludovic,

however, please provide the demo which illustrates the issue (it

Hi.
I spent some time trying to prepare a simple demo, but could not
duplicate the bug in a simple case. Sorry.
I suspect a issue related to injection of a SessionScoped bean in the
ViewAccessScoped bean, but lack a simple example.
I (or my colleague Laurent cottereau) might come back soon with a
maybe related issue, maybe on MyFaces list. We noticed a strange
behaviour with @ViewAccessScoped beans.
It seems that, under some conditions, they are not properly
instantiated/destroyed but rather recycled. Moreover, it seems that
we do not access the "right" bean in @PostConstruct or @PreDestroy.
In fact, it seems that we access a different instance of what should
be the same bean when in a call of an EL expression and in
@PostConstruct/@PreDestroy.
Oh and this bug occurs with :
- MyFaces 2.2.1
and
- CODI 1.0.5
or
- DS 0.6-SNAPSHOT (201401312 snapshot)
Working on a simple test...
I am failing to reproduce this bug in a simple test... :-( I really
tried a long time, without success. Sorry
But maybe the following stack traces and other information will help.
It seems to me that it might be an OpenWebBeans related bug... But I am
not an expert like most of you.
I heavily use @ViewAccessScoped beans. Almost all my beans are scoped
this way, excepted a few @SessionScoped beans and @ApplicationBeans.
I inject in almost all my @ViewAccessScoped a @SessionScoped bean. This
@SessionScoped bean holds undo/redo data. The @ViewAccessScoped beans
provides access to collection values in a CRUD fashions.
Most of those beans classes derive from a base
EditionContextWithoutParent class. In our case, the bean class is like
@Named
@ViewAccessScoped
public class UploadedFileContext extends
EditionContextWithoutParent<UploadedFile> {
// the @SessionScoped bean injected there
@Inject CommandContext commandContext;
...
public UploadedFileContext() {
}
@Override
public List<UploadedFile> internalGetValues() {
return Senateurs.getUploadedFilesById();
}
}
And the base class is like
@Log4j
public abstract class EditionContextWithoutParent<Type> extends
EditionContextWithTracking<Type> {
...
@Setter
List<Type> values;
public EditionContextWithoutParent() {
}
public final List<Type> getValues() {
if(values == null) {
values = internalGetValues();
}
return values;
}
@PostConstruct
public void postConstruct() {
values = null;
}
@PreDestroy
public void preDestroy() {
values = null;
}
}
If everything was working fine, there would be no need for the
upmentionned postConstruct/preDestroy methods. They are just there for
debug.
As I stated before, there are "two instances" of the same
UploadedFileContext bean in parallel.
To be more specific :
- there is a "real" instance of UploadedFileContext, which is correctly
instantiated / PostConstruct-ed / PreDestroy according to what one
expects from a @ViewAccessScoped bean
- there is a "proxied" "instance of UploadedFileContext", which does not
appear as an UploadedFileContext instance in netbeans debugger, but as a
UploadedFileContext$$OwbNormalScopeProxy0 instance.
The "proxied instance" is used in all EL calls.
#{UploadedFileContext.values} is passed as the collection to display to
a PrimeFaces p:dataTable component.
The p:dataTable component is used by a tag component, which is used in a
page using layouting with ui:composition/ui:insert.
I use :
* myfaces 2.2.1
* OWB 1.2.1
* primefaces elite 4.0.9
* omnifaces 1.6.3
The webapp is running in a Tomcat 7.0.39 container.
If I debug and set breakpoints on previously mentionned methods , I
observe the following
1) A call to UploadedFileContext$$OwbNormalScopeProxy0.getValues()
