title: sendRedirect in JSF 2.2
body: <p>I am upgrading JSF from 1.2 to 2.2 version. </p>
  
  <p>I have a simple response.sendRedirect() in my backing bean method. With JSF2.2, it started giving "java.lang.IllegalStateException: Cannot change buffer size after data has been written   at org.apache.catalina.connecto" exception.</p>
  
  <p>After adding "FacesContext.getCurrentInstance().responseComplete();", it worked!</p>
  
  <p>Can anyone help me in understanding how the implementation is upgraded in JSF2.2 that redirect is not working without explicity saying response is completed?</p>
  
  <p>Thanks!</p>
