title: Extract Field Values from Link Issues
body: <p>I want to check if the field values in the "Issues" field is null or not using a groovy script as a validator. As there are certain scenarios that will require the user to fill in this field, however not always so I cannot make it just a required field. </p>

  <p>So it would be the latter field "Issue" is what I want to see if it is null. And to be able to check the status of "Link Issue". </p>
