Cody Lerum commented on JBIDE-11899:
------------------------------------

I think it is fair to throw a warning if there is no observer to receive the injected event.

This should probably be accompanied by a @SuppressWarning type so that the user can ignore if they intend to use the event like eventLog.select(new NowLiteral()).fire();
