title: Tab refers to a missing document
body: <p>I am trying to send an envelope that is composed of 
  Template1 (1 pdf document)
  Template2 (2 pdf documents, 1-regular fill-out, 2-with attach extra document tab)</p>
  
  <p>If I use just template1 or template2 individually, I am able to send out the envelope. However, I can not send it both templates at the same time, I get the following error, and not sure what it means.</p>
  
  <pre><code>&lt;errorDetails xmlns="http://www.docusign.com/restapi" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"&gt;
  &lt;errorCode&gt;TAB_REFERS_TO_MISSING_DOCUMENT&lt;/errorCode&gt;
  &lt;message&gt;The DocumentId specified in the tab element does not refer to a document in this envelope. Tab refers to DocumentId 2 which is not present.&lt;/message&gt;
  &lt;/errorDetails&gt;
