Re: [cdi-dev] API Only PR for Context management

I think what you're asking for is to intercept at the container level and change how they initialize. I'm curious, under what cases do you not have an active request?

In addition, I think you're looking for the equivalent of Context.isActive. Part of me even wonders if swapping around the impl to be Context.activate() and Context.deactivate() may be better from a domain standpoint. What I'm looking for is a way to start contexts possibly earlier than a > specific container implementation normally starts them, and stop them > possibly later.

contexts, which you can find here: https://github.com/cdi-spec/cdi/pull/291/files

external stuff (e.g. https://github.com/apache/deltaspike/blob/master/deltaspike/modules/sched... ) so I'd like to get some input.

programmatic context starting even while on an app server. Even though I'm not using whats provided in DS, it was identified as a clear cross cutting concern hence why there's an interceptor as well.
