title: Server validation in in a single choice question
body: <p>It seems that when you send the answer to a single choice question (dropdown), Limesurvey now makes a server validation to check if the selected answer belongs to the options defined for that question at survey creation time.</p>
  
  <p>The problem is that I want to add new options via javascript, so when one of the new ones is chosen and the form is sent, Limesurvey complains that it is not a valid answer.</p>
  
  <p>Do you know how to circumvent this limitation?</p>
  
  <p>Thanks</p>
