Chris,
        I don't see the problem in the non production environment.  We did 
some more testing with our production environment.   We tested each machine 
individually and didn't see the error.    We switched on a second machine so 
we had two machines connected to the load balancer and the problem occurred. 
We tried some other lite screens and they worked fine (no error).  The 
problem seems isolated to the Group membership update lite screen.  We 
brought the third machine back into the cluster  and the problem  occurs 
consistently. 

I haven't made very many changes to the configuration files but I did change 
the  subject look in the lite ui to this
# this configures how subjects look in the lite UI.  This is the short 
version of the display
# images (must be in assets/images dir) for subject source id
grouperUi.subjectImg.sourceId.0 = ldap
grouperUi.subjectImg.image.0 = user.png
# screen EL has "subject" as an object
grouperUi.subjectImg.screenEl.0 = ${subject.id}
