defining a not storable link field from existing relation

[czcpf]

Hello,

Let's say we have EntityA, EntityB and another EntityC. How do I create a notStorable field link to EntityC in EntityA so that it can be displayed and sorted in list view. The below code works if I set entityCId and entityCName in a listLoader but sorting it doesn't work?

Custom/Resources/metadata/entityDefs/EntityA.json

{
    "fields": {​
        "entityB": {
            "type": "link",
            "isCustom":true,
        },​
        "entityC": {
            "notStorable": true,
            "readOnly":true,
            "type": "linkOne",
            "isCustom":true,
       }
    },​​
    "links": {
        "entityB": {
            "type": "belongsTo",
            "foreign": "entityAs",
            "entity": "EntityB",
            "isCustom": true
        },​
        "entityC":{
             "type": "hasOne",
             "entity": "EntityC",
             "skipOrmDefs": true
        }
    }
},

        "entityAs": {
            "type": "linkMultiple",

        },​
        "entityC": {
            "type": "link",
            "isCustom": true,
        },​
    },

        "entityAs": {
            "type": "hasMany",
             "foreign": "entityB",
             "entity": "EntityA",
             "isCustom": true
        },​

             "foreign": "entityBs",
             "entity": "EntityC",
            "isCustom": true
        },​
    }
}
