Subject [jira] [Commented] (DELTASPIKE-1199) Problems with ContextControl and Weld ContainerInitialized, ContainerShutdown event.
Date Wed, 31 Aug 2016 08:08:20 GMT

    [ https://issues.apache.org/jira/browse/DELTASPIKE-1199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15451530#comment-15451530
] 

Martin Kouba commented on DELTASPIKE-1199:
------------------------------------------

WRT the output of the first test - this is caused by the fact, that if {{CdiContainer.getContextControl()}}
is used then {{WeldContainerControl.shutdown()}} stops all contexts first (this means also
{{stopApplicationScope()}}) and after then performs the actual shutdown.

>             Project: DeltaSpike
>          Issue Type: Bug
>          Components: CdiControl
>    Affects Versions: 1.7.1
>            Reporter: Seto
>
> No replies in user mail list. So I submit an issue here. And I think it's a bug as well.
> I have an @ApplicationScoped bean. It observes ContainerInitialized and ContainerShutdown
event. 
> {code:title=Kernel.java|borderStyle=solid}
> public Kernel(){
>     System.out.println("Kernel constructed");
> }
> public void onContainerInitialized(@Observes ContainerInitialized event, @Parameters
List<String> parameters) {
>     System.out.println("container initialized");
> }
> public void onContainerShutdown(@Observes ContainerShutdown event){
>     System.out.println("container shutdown");
> }
> {code}
> Then the kernel is constructed twice with the code below, one after boot, one after shutdown.
> {code:title=Test.java|borderStyle=solid}
> public class Test {
>     public static void main(String[] args) {
>         CdiContainer cdiContainer = CdiContainerLoader.getCdiContainer();
>         cdiContainer.boot();
>         // Starting the application-context enables use of @ApplicationScoped beans
>         ContextControl contextControl = cdiContainer.getContextControl();
>         contextControl.startContext(ApplicationScoped.class);
>         // You can use CDI here
>         contextControl.stopContext(ApplicationScoped.class);
>         cdiContainer.shutdown();
>     }
> }
> {code}
> If I remove the ContextControl related code. Then it is constructed only once after boot.
> If I keep the ContextControl related code and remove the observation of ContainerInitialized.
Then it is constructed only after shutdown.
> If I keep the ContextControl related code and remove the observation of ContainerShutdown.
Then it is constructed only after boot.
> What I expect is it is constructed only once after boot even I keep the ContextControl
related code.
