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" class="">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 class=""><br class=""></div><div class="">I’d be happy if some of you could have a look and see if I missed something.</div><div class=""><br class=""></div><div class="">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 class=""><br class=""></div><div class="">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 class="">1bis) Should we decide to forbid it by default, we should provide an alternative mode to allow people using this unspecified feature</div><div class="">2) Forbid it for fireAsync()</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Thanks for your feedback and your correction if I missed the feature in the spec.</div><div class=""><br class=""></div><div class="">Antoine </div></body></html>
