Subject Re: Question on @ApplicationScoped beans
Date Mon, 14 Apr 2014 14:32:24 GMT
Hi again

Maybe I was not all clear in my question. My question is:

- In my extension class, when observering CDI container events when (when
observing what type of events) is it okay to fire an CDI event that will
reach all CDI managed beans observing the same event?

Regards
Lars-Fredrik Smedberg
