Please do not double post, if someone can help you they will answer.
The reason you're seeing that behavior is because event listeners are
solely based on the string that your event type evaluates to. So the
following 3 lines are equivalent:
addEventListener(AnswerController.SEARCH_ANSWER_ON_QUESTION, funcOne);
addEventListener(RoamerController.SEARCH_ANSWER_ON_QUESTION, funcTwo);
addEventListener("searchAnswerOnQuestion", funcThree);
As a result, any of the following would trigger all 3 functions:
dispatchEvent(new EventOne(AnswerController.SEARCH_ANSWER_ON_QUESTION));
or
dispatchEvent(new EventTwo(RoamerController.SEARCH_ANSWER_ON_QUESTION));
or
dispatchEvent(new Event("searchAnswerOnQuestion"));
In general I would recommend against having your event types
duplicated but if its unavoidable or you don't want to change it you
can just put an if(event is EventTypeWanted) at the top of the
listener (or Command in this case).
