---------------------------------------------------------------------

for me both OWB and Weld working fine (primefaces-test using Weld like Wildfly)
If you see ClientWindowScopeExtension, which is registered via 
jakarta.enterprise.inject.spi.Extension file, wildfly has to scan it actually

i cant assist you here much as im wether Wildfly dev nor user but i think MF 
does correct

maybe something like wrong beanmanager or classloader usages somewhere?

>             Project: MyFaces Core
>          Issue Type: Bug
>          Components: General
>    Affects Versions: 4.0.0
>         Environment: Windows 10, WildFly 27.0.1
>            Reporter: Manuel K

> When deploying our JSF application using MyFaces on WildFly 27.0.1, we 
> intermittently get the following exception:
> {code:java}
> org.jboss.weld.exceptions.IllegalArgumentException: WELD-001456: Argument 
> bean must not be null{code}
> I have attached the full stack trace.
> Debugging leads me to CDIUtils#get, where the following statement returns an 
> empty set:
> {code:java}
> bm.getBeans(clazz); // clazz is ClientWindowScopeContextualStorageHolder{code}
> It doesn't happen on every deployment but too often to ignore. Do you have 
> any insight on this?
> It happens whether 
> _org.apache.myfaces.annotation.USE_CDI_FOR_ANNOTATION_SCANNING_ is _true_ or 
> _false_ (just a wild experiment) and the following in the web.xml (another 
> wild experiment):
> {code:java}
>     <servlet>
>         <servlet-name>Faces Servlet</servlet-name>
>         <servlet-class>jakarta.faces.webapp.FacesServlet</servlet-class>
>         <load-on-startup>1</load-on-startup>
>     </servlet>{code}
> Thank you very much in advance!
