[cdi-dev] [JBoss JIRA] (CDI-10) Add ability to access a bean instance from a proxy

    [ https://issues.jboss.org/browse/CDI-10?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719642#comment-12719642 ] 

Stuart Douglas commented on CDI-10:
-----------------------------------

One possible use for this is dependent scoped beans that are intercepted/decorated. If these are implemented via proxying then it will not be possible to implement any form of custom injection, as it is not possible to reflect on them directly.

> There are occasions when it would be useful to access a bean instance directly from a proxy. This could be achieved by making all proxies assignable to an interface (say BeanProxy) that provides a getBeanInstance() method. 
> Client code that needs access to the actual instance can check if the object is assignable to the BeanProxy interface and then call getBeanInstance() to get the actual instance if required.
> This is something that is probably more useful to extension writers than the end user, but there have already been a few requests on the weld forum about this so it is probably worth considering.
