[weld-issues] [JBoss JIRA] Created: (WELD-933) Validator.validateBean doesn't handle @Typed properly
Validator.validateBean doesn't handle @Typed properly
-----------------------------------------------------
Key: WELD-933
URL: https://issues.jboss.org/browse/WELD-933
Project: Weld
Issue Type: Bug
Components: Bootstrap and Metamodel API, Proxies
Affects Versions: 1.1.0.CR3
Environment: JBoss 6.0.0.Final
Reporter: Mike Mosiewicz
Here is the problem.
I've got @Typed class becouse I wanted to limit the set of proxies generated by weld
becouse it's ancestors would not be proxyable. That's why I tried @Typed. And
halfway it works. But just halfway. The problem I notice is here in Validator (lines
142-145)
if (normalScoped && !Beans.isBeanProxyable(bean))
{
throw Proxies.getUnproxyableTypesException(bean.getTypes());
}
My @Typed class which is annotated like this:
@Named("catalogEntityHome")
@ConversationScoped
@Typed(CatalogEntityHome.class)
public class CatalogEntityHome extends BasicDAO<CatalogEntity, ObjectId> implements
Serializable {
..
The problem I observe is that Beans.isBeanProxyable checks
Proxies.getUnproxyableTypesException(bean) which somehow produces non-null result. However
a moment later it checks Proxies.getUnprox....(bean.getTypes()), which turns to be null.
And that's what it tries to throw, like here:
