Do the last parameter in CCNotification::addObserver works now?

cocos2d-x C++
#1

void addObserver(CCObject target,
SEL_CallFuncO selector,
const charname,
CCObject *obj);
the last parameter, if according to NSNotification, should verify the sender of the message, if obj is not null, target will not receive the message.
But it seems the implement of the function CCNotification::postNotification does not check anything about it.
Am I misunderstanding anything here? Or is it just an unsupported feature now?

#2

I got the same problem as yours. I think this is a bug. Before postNotification, it should check the last parameter.
Mail me so we could discuss more.
