Yes, I see. It's a risk making as was made, but
1) Each controller has it's own EntityManager, and is maintained on user
session - so there is one controller for each user, for each page it's
accessing;
2) It's more a exercise for API manipulation than a real use;
3) Shows that developers start to make things API designers never imagine
And this is the beauty of programming...
I will add a note about risks of doing things like this - but still a
very interesting API manipulation...
