Field validation in a set

Is it correct, that field validation, does not work in sets? I have a Repeater-field which itself contains a set of other fields. This is all working fine, but I cannot seem to validate the fields within the set.

{
  "field": {
    "type": "set",
    "options": {
      "fields": [
        {
          "name": "text",
          "label": "Text",
          "maxlength": "200",
          "required": true,
          "type": "text"
        },
        ...
      ]
    }
  }
}

Neither shows me an error when the field is empty, nor when I enter more then 200 characters.

Is there no possibility to validate fields listed in a Set?

I’m not sure right now, if validation works inside sets and repeaters - but if or if not, you have to adjust your field options a little bit so the nested fields receive their options properly:

{
  "field": {
    "type": "set",
    "options": {
      "fields": [
        {
          "name": "text",
          "label": "Text",
          "type": "text",
          "options": { // <-- nested field options
            "maxlength": "200",
            "required": true,
          }
        },
        ...
      ]
    }
  }
}

As always spot on. Thanks!
