ExtJS 6 inherited hasMany-Relation nested loading - extjs

Question

I try to setup a hasMany relationship and want load my main entity with all the associated models in a single request.
But that seems not to work with "hasMany" relations that is inherited.
I have a BaseModel that defines all relations and fields and a "normal" model that defines the proxy to load from.
These are my (relevant) models:
Ext.define('MyApp.model.BaseUser', {
"extend": "Ext.data.Model",
"uses": [
"MyApp.model.UserEmail",
"MyApp.model.Account"
],
"fields": [
{
"name": "name"
},
{
"name": "accountId",
"reference": {
"type": "MyApp.model.Account",
"role": "account",
"getterName": "getAccount",
"setterName": "setAccount",
"unique": true
}
}
]
"hasMany": [
{
"name": "emails",
"model": "MyApp.model.UserEmail"
}
],
});
Ext.define('MyApp.model.User', {
extend: "MyApp.model.BaseUser",
proxy: {
type: 'rest',
url : '/api/user',
reader: {
type: 'json',
rootProperty: 'data',
}
}
});
Ext.define('MyApp.model.UserEmail', {
extend: 'Ext.data.Model',
"fields": [
{
"name": "id",
"type": "int"
},
{
"name": "email",
"type": "string"
},
],
proxy: {
type: 'rest',
url : '/api/user/email',
reader: {
type: 'json',
rootProperty: 'data',
}
}
});
// MyApp.model.Account looks like MyApp.model.UserEmail
This is my server's response:
{
data: [
{
name: 'User Foo'
accountId: 50
account: {
id: 50,
balance: 0
},
emails: [
{
id: 70,
email: 'hello#world.de'
}
]
}
]
}
The "account" relation is working on the "normal" User Model and I can access it via the auto-generated method user.getAccount() as I expected.
Now I tried to access the users emails with the auto-generated methods:
// user is of 'MyApp.model.User'
user.emails(); // store
user.emails().first(); // null
user.emails().count(); // 0
It seems that the "emails"-relation models were not loaded into my user model. Am I accessing them the right way?
I can access them via user.data.emails. But this is an array of plain objects, not of UserEmail-Objects.
Can anyone give me some advice? Is nested loading supported with keyless associations?
Kind regards,

Clearified what I ment.

It should work. Here's a working fiddle. Check console for nested loaded data.
