@Antoine: didnt complain about the in progress status. Just prefer as Jozef to not put something we ll revert which will lock us as @New did but in a worse manner. Said otherwise better to not do than doing it wrong knowing it is wrong.2015-06-24 11:39 GMT+02:00 Antoine Sabot-Durand <antoine@sabot-durand.net>:Romain,CDI-26 was open 4,5 years ago. Obviously working on the whole stuff in one shot didn't made it. To get out of the dead end I didn't see other solution than to cut the features in smaller pieces. That's why it's not finished and I intend to explain it in my blog post. As I'll explain that the EDR is for testing not early adoption.Le mer. 24 juin 2015 à 11:31, Antoine Sabot-Durand <antoine@sabot-durand.net> a écrit :Jozef,I think I really got your disagreement on that point. You repeated it many times.My point and the question I keep asking to you is "what is your suggestion?".Personally I see 5 solutions here:1) Don't do anything since there's no alternative solution2) Change the wording regarding request scope activation in something like "is active from the initialization of the container until its shutdown"3) Give the same behavior than application scope request scope is shared4) Revert and say that Request Scope is not active in SE. But it's also a hack since we'll change it with CDI-5305) Don't specify anythingI guess that you're choice is 4 or 5, but I may be wrong again, so why not tell us what you'd like to see and save us some time ?thanksAntoineLe mer. 24 juin 2015 à 11:13, Mark Struberg <struberg@yahoo.de> a écrit :Jozef, read the rest of the meeting minutes as well. Throne and I enlisted dozen of REAL use cases where it is needed.

Yes it does. In the final spec a programmer could programmatically enable the request context and ends it again IF he needs it. But today he cannot. And many users code really needs it. So the only thing we can do TODAY is to enable it by default.

Well that is an option but the users then cannot rely on it.
And no, it is perfectly implementable as it is worded right now.
