Validation not work with auto-form


#1

my simple form to edit user profile

<template name="dashboard">
    {{#autoForm collection='Meteor.users' doc=currentUser type='update' id='accountForm'}}
      {{> afQuickField name='profile.name' autofocus=''}}
      {{> afQuickField name='profile.bio' rows=5}}
      <button type='submit' class="btn btn-primary">Update</button>
    {{/autoForm}}
</template>

why form is submited if fields is empty? i set optional: false in scheme!
data not saved, because i get error

 {error: 400, reason: "INVALID", details: "[{"name":"profile.name","type":"required","value":null}]", message: "INVALID [400]", errorType: "Meteor.Error"}

my form have attribute novalidate=“novalidate” WHY? i aslo set validation=“submit”
