title: Is this the first time the user is being asked? - Get the prompt number for a question in Bot Framework Composer
body: <p>So I have some questions in Bot Framework Composer 2.x that can be interrupted. No problem.</p>
  <p>If the user interrupts, the interruption is dealt with and then the initial question is re-asked.</p>
  <p>I want to know how to detect whether this is the first time the question is asked or not.</p>
  <p>I thought this.turnCount might be it, but it seems always to be 1.
  For one question, dialog.eventCounter works: it reads 1 the first time and a higher number the second. But for other questions, it always reads 1.</p>
  <p>So. Welcome thoughts on a <strong>reliable way to tell if it is the first prompt of a question</strong>.</p>
