Error description

  • ?If MyFaces 2.2 is loaded at the server level, MyFaces CDI
    support is set once per server. This causes CDI-enabled JSF
    applications to not work properly if a non-CDI application
    is loaded first.
    
    Steps to reproduce the error on WebSphere Liberty
    1. Enable the jsf-2.2 and cdi-1.2 features on the WebSphere
    Liberty server.
    2. Deploy two JSF applications: one that uses CDI (for
    example, a flow built using FlowBuilder) and one that does
    not use CDI.
    3. Make a request to the non-CDI application first. The
    message 'MyFaces CDI support disabled' should be written to
    the
          logs.
    4. Make a request to the CDI-enabled application. If testing
    an application with a flow built using FlowBuilder, the flow
          will not be discovered.
    
    Investigation has found that MyFaces has two conditions to
    determine CDI availability:
      1. CDI must be found on the classpath
      2. The application map must have a bean manager instance
    (Found inside
    org.apache.myfaces.util.ExternalSpecifications#isCDIAvailabl
    e()).
    
    When MyFaces is shared between different applications,
    basing CDI availability on an application's configuration
    (condition two) is an issue.

    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty Profile - JavaServer Faces   *

    * PROBLEM DESCRIPTION: ?MyFaces Contexts and Dependency        *
    *                      Injection (CDI) support is disabled if  *
    *                      a non-CDI application is loaded first.  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    JSF CDI support is set once per server. This can cause JSF
    features that need CDI (for example, Faces Flows) to not work in
    if a non-CDI application is loaded first.
    

Problem conclusion

  • The JSF MyFaces 2.2 code was updated so that MyFaces CDI support
    is set for each JSF application.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 16.0.0.2.  Please refer to the Recommended Updates page for
