[cdi-dev] Question about section 4.2

[John D. Ament]

Ok, so I was able to reproduce my issue, but it doesn't match Aslak's case.

https://github.com/johnament/cdifoo

It's a very simple project.  I used AS7 as my deployment container.

In one test, I use beans.xml to autoregister the archive.
That passes fine.

In the other test, I don't use a beans.xml, instead I use

public void addHandlers(@Observes BeforeBeanDiscovery bbd,BeanManager
beanManager) {

to register the classes in my archive.  I even go the extra step of
registering my interface and test case, just in case.

Could you take a look at the project and let me know if you see something I
did wrong?

- John
