Question

I’ve a little problem, I don’t really understand if I can use addEventListener more than one time on the same object (and same callback function) if this case can I have a problem of overflow, or simple flex is so smart to not add again in the same stack same function

for examples:

var t:CServiceObj = _rModel.userGetBoardJoined(); 
t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk);
t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk);
t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk);

Answer 1

As you say, Flex is “smart” and even if you subscribe to an event more than once on the same instance, then the handler will be called Just once (no matter how many addEventListener you pass).
