Configuration options not shown

[lsiepel]

While developing a new binding for Zwave-JS, i have some difficulties trying to dynamically add configuration options. The options are added to the REST response, but the UI does not render them.

Using the ConfigDescriptionParameterBuilder.withOptions results in:

{
            "context": "item",
            "description": "Once activated, Wall Plug will keep a connected device ...",
            "label": "Always On Function",
            "name": "configuration-function",
            "required": true,
            "type": "INTEGER",
            "readOnly": false,
            "multiple": false,
            "advanced": false,
            "verify": true,
            "limitToOptions": true,
            "options": [
                {
                    "label": "Activated",
                    "value": "0"
                },
                {
                    "label": "Inactive",
                    "value": "1"
                }
            ],
            "filterCriteria": []
        }

No dropdown is shown:

The console does not show any related errors.
