NOTES:
EG (9/24/2001 8:14:46 AM)
	moving to JCORE FYI

PM (9/25/2001 12:52:12 PM)
	Could be some client code asking questions to a discarded Java element, and not protecting itself from the resulting exception.
	Back to ITPJUI.

EG (10.10.2001 22:26:29)	
	pls investigate

Comment 1 Martin Aeschlimann

The walkback is the problem discribed in
   4113: Type Hierarchy does not update when class added (1GII73E) 
   (updates should be posted)
But due to problems described in 
   3420: 1GKXGAT: ITPJCORE:WINNT - Problem with order of change listeners
I cant solve this, except for a workaround

Comment 2 Martin Aeschlimann

fixed > 11025.
workaround with mannually making sure that the element listener is added after 
the typehierarchy listener.

I still think JCore should do something.
