  Modified:    applications/pam/src/java/org/apache/jetspeed/portlets/pam
                        PortletApplicationDetail.java
  Log:
  attempting to get add/update/delete on  user attribute
  this is having some very strange side effects:
  
  add one attribute, ok
  add a second attribute, adds the second ok, but also adds the previous attribute again
  add a third attribute, ands the third attribute ok, but also adds the previous two attrbutes again
  and so forth
  
  think we need some unit tests for these simple cases
