@Produces returning null
if @Produces can produce null e.g.
@Produces
@Default
@RequestScoped
public KeycloakSecurityContext keycloakSecurityContext() {
if (httpServletRequest.getUserPrincipal() instanceof
KeycloakPrincipal) {
KeycloakPrincipal<KeycloakSecurityContext> keycloakPrincipal =
(KeycloakPrincipal<KeycloakSecurityContext>)
httpServletRequest.getUserPrincipal();
return keycloakPrincipal.getKeycloakSecurityContext();
}
return null;
}
then i get
Caused by:
javax.enterprise.inject.IllegalProductException - WebBeans producer :
keycloakSecurityContext return type in the component implementation
class : uk.me.kissy.external.producers.SecurityProducer scope type must
be @Dependent to create null instance
at
org.apache.webbeans.util.WebBeansUtil.checkNullInstance(WebBeansUtil.java:902)
I can't add @Dependent to the KeycloakSecurityContext class but if I add
it to keycloakSecurityContext() i get
org.apache.openejb.cdi.OpenEJBLifecycle.startApplication CDI Beans
module deployment failed
org.apache.webbeans.exception.WebBeansConfigurationException:

Posted by Matthew Broadhead <ma...@nbmlaw.co.uk>.
also i did not realise that @Dependent is a Scope. so i was declaring
@RequestScoped and @Dependent at the same time

Re: @Produces returning null
Posted by Matthew Broadhead <ma...@nbmlaw.co.uk>.
looks like it. another method was injecting the security context, so i
moved it to it own class and now it is working. changing from
@ApplicationScoped to @RequestScoped must have uncovered the problem. i
set everything to requestscoped now because all only produce on request

Re: @Produces returning null
Posted by Romain Manni-Bucau <rm...@gmail.com>.
Hi
it looks accurate, a normal scoped instance - request scoped - proxies
a not null instance so you can't return null. Using a @RequestScoped
producer class (the enclosing one) and @Dependent producer can work
too if you inject this context in request scoped instances only.
