[DataForm] unable to create editor of type DatePicker or TimePicker, while using metadata

[tsonevn]

An issue while generating editor of type DatePicker or TimePicker, while using metadata. For example:
HTML

<RadDataForm tkExampleTitle tkToggleNavButton  #myDataForm [source]="person" [metadata]="personMetadata"></RadDataForm>

Typescript

this.person={
    "name": "John",
    "age": 23,
    "email": "john@company.com",
    "city1": "New York",
    "street": "5th Avenue",
    "streetNumber": 11,
    "datefield":"2016-05-06"
    }
this.personMetadata = {
  "isReadOnly": false,
  "commitMode": "immediate",
  "validationMode": "immediate",
  "propertyAnnotations":
  [
    {
      "name": "name",
      "displayName": "Name",
      "groupName": "Main"
    },
    {
      "name": "age",
      "displayName": "Age",
      "editor": "Number",
      "groupName": "Main"
    },
    {
      "name": "email",
      "displayName": "E-Mail",
      "editor": "Email",
      "groupName": "Main"
    },
    {
      "name": "city1",
      "displayName": "City1",
      "editor": "Picker",
      "valuesProvider": ["New York", "Test", "Los Angeles"],
      "groupName": "Main2"
    },
    {
      "name": "street",
      "displayName": "Street Name",
      "groupName": "Main2"
    },
    {
      "name": "streetNumber",
      "displayName": "Street Number",
      "editor": "Number",
      "groupName": "Main2"
    },
    {
        "name": "datefield",
      "displayName": "datefield",
      "editor": "DatePicker",
      "groupName": "Main"
    }
  ]
}

Error:

-[__NSCFString isEqualToDate:]: unrecognized selector sent to instance 0x600000a46240

A workaround is to repete the DatePicker on the HMTL, like here : https://github.com/maatthc/ns_dataform

The fix is released in nativescript-ui-dataform@3.8.
