To reproduce this, you have to remove the list of pages then do
Browser... 
The NPE means j2eeserver get notified on a ddbean event given old
value BaseBean's without parent.  Generally, event base beans except
root should be part of a graph.  In this case probably the event was
generated even the removed values (which are just default) have not
been known to the ddbean cache yet.  Just protect j2eeserver from such
bad event.  Fix checkin:
