title: How to always validate an angular json schema form?
body: <p>I am using <a href="https://github.com/json-schema-form/angular-schema-form" rel="nofollow">angular-schema-form</a>, and ran into a problem that when I load a schema and a form from a server using REST, the validation sometimes did not kick in. I could post a schema even though some fields were required.</p>
  
  <p>How can I always be sure that the required fields in the form has to be filled in by the user before posting?</p>
