EventHandler triggered by some channels and not from some others

[francestu96]

I want to listen to some channels and, after a successful client.start() authentication, I make:
client.addEventHandler(msgHandler, new NewMessage({ incoming: true, chats: [<my_channels>]]));

For some reason, some channels does not trigger the msgHandler function. What could it depends on?

Thank you in advanced!
