What's the issue w/ fire async and mutable payload? Non-deterministic behavior depending on thread?<br><br><div class="gmail_quote">On Tue Dec 16 2014 at 11:32:53 AM Antoine Sabot-Durand <<a href="mailto:antoine@sabot-durand.net">antoine@sabot-durand.net</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">Hi guys,<div><br></div><div><br></div><div>Always working on Async event concept and discussion around mutable payloads. I was looking where in the spec we specified the fact that fired payload are mutable. I red-read chapter 10 (<a href="http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#events" target="_blank">http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#events</a>) twice and didn’t found. I also browsed JIRA and TCK to find any ref to this feature and found nothing. On the other hand it is not specified that payload should be immutable ;)</div><div><br></div><div>I’d be happy if some of you could have a look and see if I missed something.</div><div><br></div><div>If I’m not wrong, the mutable payload we (including myself) advertise in CDI is a non portable feature (I’m the firs surprised here). So I propose that :</div><div><br></div><div>1) We decide to write something in the specification about allowing or forbidding it (I know some people not happy with this mix between observer and visitor pattern)</div><div>1bis) Should we decide to forbid it by default, we should provide an alternative mode to allow people using this unspecified feature</div><div>2) Forbid it for fireAsync()</div><div><br></div><div><br></div><div>Thanks for your feedback and your correction if I missed the feature in the spec.</div><div><br></div><div>Antoine </div></div>______________________________<u></u>_________________<br>
