GemStone Forwarders Do Not Support VisualWorks ValueHolders
When a ValueHolder holds a forwarder to a GemStone object, operations
performed on the ValueHolder from the VisualWorks screen can successfully
create, save, and modify the object in GemStone. However, the GemStone
server object does not send a message back the ValueHolder telling it
that the object to which it points has changed. As a result, the
VisualWorks screen does not redraw itself to properly reflect the
GemStone object change.
