The JavaServer Faces support that originally shipped in WebSphere® Studio Application Developer V5.1.2 has been updated for Rational® Application Developer V6.0. If you want to continue developing in V6.0 portlet projects that were created with Portal Toolkit 5.0.2.2 on WebSphere Studio Application Developer V5.1.2, it is recommended that you upgrade the Faces project runtime resources to the latest levels.
