deferencing pointer/object and code completion (Qt creator 3.4.1)

[Longin Kandinsky]

Hello,
I will start with example:
map<string, vector<int> > references;
map<string, vector<int> >::const_iterator iter = references.begin();
vector<int>::const_iterator vec_iter = iter->second.begin();
//_____________________________________________ ^ at this point I expect pop-up with suggestions but nothing happens (CTRL + SPACE does nothing)
Should it work or it isn't implemented?
