Error description

• JSP 1.2 Portlet on WebSphere Portal 8 implementation as
  MyFaces generates incorrect markup
  
  
  Facelet page is generated on WebSphere Portal 8 without any
  problem, but portlet with jsp page generates span tags .
  
  <span
  id="viewns_Z7_I2M6H2O0JG4F10AON0UP2H1043_:ns_Z7_I2M6H2O0JG4F10AO
  N0 UP2H1043_j_id1">
  <p>First paragraph.</p>
  <p>
  </span>
  <span id="viewns_Z7_I2M6H2O0JG4F10AON0UP2H1043_:text1"
  class="outputText">Hello this is jsp page!</span><span id="
  viewns_Z7_I2M6H2O0JG4F10AON0UP2H1043_:
  ns_Z7_I2M6H2O0JG4F10AON0UP2H1043_j_id2">
  </p>
  <p>Last paragraph.</p>
  </span>
  
  The current behavior is to prefix the portlet namespace to
  component IDs, which causes JSF to render unnecessary span
  tags (because it thinks that the ID attribute should be saved.)
  

Local fix

• This issue is fixed with a change to the unique
  ID generation code in MyFaces
  Disabling that prefixing stops the incorrect span rendering.

  ****************************************************************
  When using WebSphere Portal Server with JSF MyFaces, elements
  (such as plain HTML) can be assigned incorrect unique
  IDs - which cause MyFaces to render span tags around the
  elements.  For example,
  <p>Text</p>
  might be rendered as
  <span id="viewns_some_id_:j_id_1"><p>Text</p></span>
  which is incorrect.
  This problem was caused by MyFaces prefixing external
  namespace IDs to unique IDs.
  

Problem conclusion

• The JSF MyFaces code was updated to assign unique IDs properly.
  To enable this behavior, set the following context parameter
  to "true": com.ibm.ws.jsf.DISABLE_UNIQUE_ID_NAMESPACE_ENCODING
  (true/false-default).
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.10 and 8.5.5.4.  Please refer to the
