Re: Idea of RequestFactory
You could add the with("address") to the findAll call:
requestFactory.personRequest().findAll().with("address").fire(...);

Well, it seems that there is a bug probably or I am doing something
wrong, because my previous instance does not get updated. Still
calling getAddress() returns 'undefined', however in newly fetched
Person entity calling getAddress behaves as expected - address is
returned.
Best regards!

AFAICT, actually, when doing your second request
(find(personId).with("address")), the previous entity proxy will be
updated; i.e. for each proxy there's a "canonical", immutable instance
that's being updated in place when a response comes back from the
server, and there are "editable" instances bound to a RequestContext
after a call to the RequestContext's edit() method (the editable/
mutable instance is cloned from the canonical one at the time edit()
is called).
This is at least what I understand from reading the source of
AbstractRequestFactory, AbstractRequestContext and AbstractRequest.

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!

When querying the server, RequestFactory does not automatically

In your case, you'd have to do a with("b"), as your property is named
getB(). it works the same whichever the type of the property (B,
List or Set).

Idea of RequestFactory
Hi! I am playing around with new RequestFactory feature available in 2.1, and actually I think that I don't get the idea. At first i thought, that RequestFactory will bring me something like local domain model. Lets assume that entity A and proxy for it are present. Lets assume that this entity A has method getB() that returns entity B (proxy for this entity is also present). Now when I request for object A it is returned, but calling getB() causes "undefined" error. I would expect that this entity will be get from the server. Or I could load this entity B explicitly, but when I do this entity A still knows nothing about B. I can load again A with B, but this will give me whole new instance of A. I thought that it will be automatic or semiautomatic consistent local domain model. I cannot load all As with all Bs, because in my GUI user only selects one A, and for this A I will need its Bs. Getting all As and all Bs at start will cause loading lots of data. I need to build a model that is updated with new parts from server depending on what actions user takes. What am I missing?
