[weld-issues] [JBoss JIRA] Reopened: (WELD-907) bean-lookup issue in Context#get(Contextual, CreationalContext)

[Gerhard Petracek (JIRA)]

     [ https://issues.jboss.org/browse/WELD-907?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gerhard Petracek reopened WELD-907:
-----------------------------------



stuart, that's irrelevant in this case.
#1 there is no producer in this case
#2 there is only one bean in the whole (demo-)app
#3 the component passed to the context implementation has to provide the correct bean-class and qualifiers to lookup the bean again with those information.

since it looks like that it works (again) with glassfish 3.2, you can resolve it (fixed) but not with rejected.

>             Project: Weld
>          Issue Type: Bug
>          Components: Scopes & Contexts
>    Affects Versions: 1.1.1.Final
>            Reporter: Gerhard Petracek
>            Assignee: Stuart Douglas
>             Fix For: 1.1.2.Final

> this is a very special case which used to work before weld v1.1.1
> e.g.:
> Set<Bean<?>> beans1 = beanManager.getBeans(MyBean.class);
>         
> Class beanClass = beans.iterator().next().getBeanClass();
> Set<Annotation> qualifiers = beans.iterator().next().getQualifiers();
> Set<Bean<?>> beans2 = beanManager.getBeans(beanClass, qualifiers.toArray(new Annotation[qualifiers.size()]));
> beans1 is the same as beans2
> that works without problems.
> if you use the same in 
>   Context#get(Contextual, CreationalContext)
> it doesn't work. i haven't looked at the details but it might be due to the performance optimizations.
> the following example isn't that useful (so please don't ask for the reason) - it's just the minimal code to reproduce the issue.
> public <T> T get(Contextual<T> component, CreationalContext<T> creationalContext)
> {
>   Class beanClass = ((Bean<T>)component).getBeanClass();
>   Set<Annotation> qualifiers = ((Bean<T>)component).getQualifiers();
>   Set<Bean<?>> beans = CdiUtils.getBeanManager().getBeans(beanClass, qualifiers.toArray(new Annotation[qualifiers.size()]));
>   //beans is empty
> }
> it isn't specified that it should work but it used to work with weld and it also works with owb.
> since there is (imo) no reason why it shouldn't work, it would be great if it gets fixed!
