Custom Layout for List view of controller

[onepoint0]

Hi Devs,

I have an entity - mmxProduct - with a type field on it that can have one of two different types - Lite or Pro. I have two custom controllers which show a subset of the entity records depending on the type. The controllers look like this:

define('custom:controllers/mmx-lite', ['controllers/record'], function (Dep) {

    return Dep.extend({

        entityType: 'MmxProduct',

        getCollection(usePreviouslyFetched) {
            console.log(`controller for Mmx product - mmx lite type`);
            return Dep.prototype.getCollection.call(this)
            .then(collection => {
                console.log(`in then`);
                collection.whereAdditional = [
                    {
                        field: 'productType',
                        type: 'equals',
                        value: 'Lite', // <-- this is set to 'Pro' on the other controller
                    }
                ];
                return collection;
            });
        }

    });
});​ 

The where condition is Lite for one and Pro for the other and the two screens successfully show only their own subset of records.

I have corresponding clientDefs files for each of the controllers that point to the controller files eg

{
    "controller": "custom:controllers/mmx-lite",
    "boolFilterList": [
        "onlyMy"
    ],​
    ....

My problem is I want to show a different list layout for each of these screens - the pro version of the product has a field that is not present on the Lite version and I want to omit that field altogether from Lite list. Currently both screens use the list.json layout of the entity (the default behaviour).

I have tried doing this with a custom list view but it doesn't seem to have access to the layout. I've looked through the code to find ways to do it, but I can't find anything.

Does anyone know how I can do this?

Thanks,
Clare
