Infopath - get user properties (e-mail, department.. ) from a people picker - other than current user

I've tried to follow this link http://ift.tt/1vyZ69J to get user properties, but I only get properties from my current user.

Is there a way to pick a user from a people picker and then populate the properties?

I found a youtube movie that does what I want but I it doesn't work. http://ift.tt/1yKHvS6 . Could It be somthing with the environment?
