OK, but lets assume this:
At the beginning there are lots of Person entities. I don't need their
addresses until user choses one particular Person entity. So at the
beginning I do:

requestFactory.personRequest().findAll();

Then, user chooses one particular Person entity and this is a moment
when I need address entity. I can do:

requestFactory.personRequest().find(personId),with("address");

But this will cause:
1. Getting of Person entity which I already hold.
2. Creating new instance of Person entity and I have to look after
proper instance, as the old one does not contain address.

Is there any other way to solve this without above side effects?

Best regards!
