Mark Struberg commented on CDI-129:
-----------------------------------

Jozef, thanks for your input so far. There are some valid points in your argumentation and we need to clarify those. I guess we now have a pretty clear picture that EAR scenario is broken in CDI 1.0 if we use scopes broader than 1 contextual instance per war.

We also outlined 3 different approaches to treat such scopes. We will schedule an EG meeting to discuss this in the EG.

Pete, do you have the example app somewhere so we can look at the sources?

> Since @ApplicationScoped currently is defined in 6.5.2 as to be 'like in the Servlet specification' this means that you will get a new instance for every WebApplication (WAR file).
> There is currently no specified CDI scope for providing a single shared instance for a whole EAR.
> We could (ab-)use @Singleton for that, but this is currently not well defined at all.
> Alternatively we could introduce an own new annotation like @EnterpriseScoped or likes.
