PM02622: CONFIGURING 'DESCRIPTION' ATTRIBUTE IN AUTHORING AS DISPLAY ATTRIBUTE causes classcastexception

APAR status

• Closed as program error.

Error description

• Changing the display attribute in Authoring is done by adding
  the following property in WCMConfigService.properties :
  connect.usermanagement.usecnfordisplayname=false
  connect.usermanagement.usercommonnameattribute=<attribute>
  connect.usermanagement.groupcommonnameattribute=<attribute>
  ( http://www-01.ibm.com/support/docview.wss?uid=swg21385492 )
  
  However configuring the display attribute as 'description'
  fails .
  'description' is a multi-value attribute, while WCM is expecting
  a single-vallued attribute .
  
  Traces show similar to :
  [11/6/09 10:44:08:802 CET] 00000060 UserUtils     <
  com.presence.connect.wmmcomms.UserManagementUtils
  getUserAttribute RETURN [GROUP NAME]
  [11/6/09 10:44:08:803 CET] 00000060 SystemErr
  R java.lang.ClassCastException: java.util.ArrayList incompatible
  with java.lang.String

  com.presence.connect.wmmcomms.UserUtils.getUserSingleValueAttrib
  ute(User Utils.java:799)
  

Local fix

• Use single-value attribute instead
  

Problem summary

• Problem Summary: ClassCastException encountered when changing
  user/group display attribute
  

Problem conclusion

• Problem Description:
  In WCM, administrators can change the puma attribute that is
  used as the display attribute
  for users and groups within WCM.  This is changed using the
  following properties:
  
  connect.usermanagement.usercommonnameattribute
  connect.usermanagement.groupcommonnameattribute
  
  If the administrator changes this value to something that is
  multivalue within the portal
  user architecture, a classcastexception can occur.
  
  For example:
  
  [11/6/09 10:44:08:803 CET] 00000060 SystemErr R
  java.lang.ClassCastException: java.util.ArrayList incompatible
  with
  java.lang.String
  [11/6/09 10:44:08:804 CET] 00000060 SystemErr R at
  com.presence.connect.wmmcomms.UserUtils.getUserSingleValueAttrib
  ute(User
  Utils.java:799)
  
  Problem Analysis: WCM expecting display name to be a single
  value attribute.  In the
  case above, customer had used attribute Description that was
  multivalued.
  
  
  Problem Solution: WCM changed to handle the situation
  

Temporary fix
