Description Scott Delap CLA 2006-02-08 15:30:37 EST 
NestedUpdatable value attempts to retrieve the old value of the previous inner updatable it holds while building a change event for the new value.  The issue with this is that the object graph refrences by the old values may have become corrupt (which is why the nested updatable is being changed).  At minimum the code to retreive the old value should be more resilient perhaps defaulting to null for the old value if an exception is thrown.
Comment 1 Boris Bokowski CLA 2006-02-08 15:43:25 EST 
...or maybe the old value needs to be cached?
Comment 2 Scott Delap CLA 2006-02-08 15:55:21 EST 
That would be another good default if the old value can't be retrieved.
Comment 3 Boris Bokowski CLA 2007-06-26 15:37:01 EDT 
Is this still a problem?
Comment 4 Matthew Hall CLA 2009-01-21 20:42:01 EST 
Obsolete?

I guess so.
