Hi guys, i spot a problem with my custom control on Umbraco 8.9.0 which is defined like this.

{
  "alias": "node-picker-63",
  "hideLabel": true,
  "view": "contentpicker",
  "editorAlias": "Umbraco.MultiNodeTreePicker",
  "config": {
    "filter": "",
    "maxNumber": 12,
    "minNumber": 1,
    "multiPicker": true,
    "returnType": "Id",
    "showEditButton": false,
    "showPathOnHover": false,
    "startNode": {
      "type": "content",
      "id": null,
      "query": null
    },
    "type": "content"
  }
}

Problem is that despite using preview attribute set to true, the validation still occurs if i set min element to 1. With Umbraco.MultiUrlPicker that problem does not occur. Preview works as i cannot add any element in this view, but validation too.

<umb-property-editor model="field.control.value" preview="true" ng-if="field.control.value"></umb-property-editor>

MultiNodeTreePicker is defined like this

{
  "name": "Multi Url Picker",
  "icon": "icon-link",
  "editorAlias": "Umbraco.MultiUrlPicker",
  "view": "multiurlpicker",
  "config": {
    "minNumber": 1,
    "maxNumber": 12,
    "ignoreUserStartNodes": false,
    "hideAnchor": false
  }
}

There is no problem with save of this control.

I don't know how but my value in my custom control is validated if there is more than one element as for example if i define it with value: {}, the validation will pass. However in the place where this field would be mandatory and not in preview the validation will not occur too.
