title: jsf primefaces reset the wizard and set all values to null
body: <p>I am using prime faces wizard with three tabs, each tab is dependent on the previous one, when I reach the last one I have a button that takes the user back to the first tab, my code works but the problem is I have a selectOneMenu that has a values from a dataTable and I would like to set to null but I keep getting what I have chosen before. I have tried the following code:</p>
  
  <pre><code>    RequestContext.getCurrentInstance().update("frmExamBank");
      setCourseExamBank(null);
      RequestContext.getCurrentInstance().reset("frmExamBank");
  </code></pre>
  
  <p>But nothing worked for me, I keep getting the same values and when I choose a different dataTable item it does not change in the next tab but it gets my old value.</p>
  
  <p>Can someone advice.</p>
