Waldir, you should not get any notifications if you've the chat-application focused.
Nick, discussing user-interaction rationale on bugs is not very helpful. This is very off-topic looking at the initial bug-description anyway. This should happen on the ayatana mailing-list. The reasoning for why notifications behave the way they do you can find https://wiki.ubuntu.com/NotifyOSD ("Rationale" and "Use cases"). Please read that and move any further questions to the ayatana mailing-list.
