Is it possible for Jaydata relationships to function seamlessly without the need to be

I am attempting to set up a basic model with Parent -> Child relationships (correctly declared and functioning, I believe).

This is my approach:

var parent = new $data.Types.Parent();
$data.context.Parents.add(parent);
parent.Code = 123;

var child = new $data.Types.Child();
$data.context.Childs.add(child);
child.Parent = parent;
child.Value = 456;

However, when trying to access parent.Childs, it returns undefined instead of the array containing the added child.

After saving both entities using:

$data.context.saveChanges();

Upon accessing parent.Childs again, I now get the array [Child]

Having used other ORM tools in the past, it appears that jaydata does not support accessing relationships before saving?

In need of clarification. Thank you!

EDIT:

Observing code on stackoverflow, it seems that I must manually create the Childs array like so:

var parent = new $data.Types.Parent();
$data.context.Parents.add(parent);
parent.Code = 123;
parent.Childs = new Array();

var child = new $data.Types.Child();
$data.context.Childs.add(child);
child.Parent = parent;
child.Value = 456;

parent.Childs.push(child);

Can anyone confirm if this is indeed the correct method for utilizing relationships in jaydata?

Failing to include the child in the parent element means that assigning the parent id alone will not automatically place the child in another array.
