Subject [jira] [Commented] (EXTCDI-304) CODI @ConversationScope + @Stateful in a bean = java.lang.StackOverflowError
Date Sat, 15 Dec 2012 14:56:12 GMT

    [ https://issues.apache.org/jira/browse/EXTCDI-304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13533044#comment-13533044
] 

Eric Covener commented on EXTCDI-304:
-------------------------------------

posted to the OWBN ticket:;

AFAICT WSEjbBean is calling Context.get with no CreationalContext to test if an instance is
already in the scope, but it looks like the custom scope is trying to create a new instance,
which si where it then loops.

> The get() method may not create a new instance of the given contextual type unless a
CreationalContext is given.

>             Project: MyFaces CODI
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.0.5
>         Environment: WebSphere v8.5.0.1 on Windows (With OWB + MyFaces internally)
>            Reporter: Denis Forveille
>
> In WebSphere v8.5.0.1 this very simple bean causes a java.lang.StackOverflowError :
> @Named("codiTestConversationCtrl")
> @ConversationScoped
> @Stateful
> public class CODITestConversationCtrl implements Serializable {
>    private static final long serialVersionUID = 1L;
>    private Integer           valeur;
> <whatever code from her, getters/setters etc>
> It is referenced in a page with
>    #{codiTestConversationCtrl.valeur}
> This causes a StackOverflowError after an endless recursive loop . 
> If i use the CDI @ConversationScoped standard annotation instead of the CODI one, it
works
> If I remove the @Stateful annotation to use a plain POJO instead of a SFSB, it works
too..
