  ****************************************************************
  When using JSF 1.2 and redirecting to an external Portal
  page the encodeActionURL is invoked in action phase and
  causes an execption during creation of action URL which
  happens during the render phase.
  

Problem conclusion

• Handled the invocation of encodeActionURL during action
  phase and configured the absolute URL to portal page.
  
  The fix for this APAR is included in Rational Application
  Developer v8.0.4.
