Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server Versions   *
  *                  8.0 and 8.5 users of JavaServer Faces(JSF)  *
  *                  MyFaces.                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: CDATA sections wrapping JavaScript      *
  *                      code on a page are lost.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  For example if an application contains a page with:
  <script type="text/javascript">
  //<![CDATA[
  // JavaScript code ...
  if (345 > 34)
  {
  // JavaScript code ...
  }
  //]]>
  </script>
  The CDATA section is lost and the "greater than" sign is
  evaluated to &gt therefore not giving the expected behavior.
  The page incorrectly looks like the following:
  <script type="text/javascript">
  // JavaScript code ...
  if (345 &gt; 34)
  {
  // JavaScript code ...
  }
  </script>
