Hi youngho,
How is Chosen? This is no doubt oversimplified, but if I understand
your question, you are losing the referenced object when you load the new
instance and reset the object reference, which is normal.
If possible, you should check what the client requested first, then load
your new instance only of they are asking for different data, i.e. don't
blindly load the new instance, otherwise use the old instance.
If the former is not possible for some reason, have another object
reference and set it to the instance at the end of your operations on the
current set:
somedataref = HT;
..... // do work
olddataref = somedataref;
Then when you discover the client wants 'more detailed info' either use
the old one directly, set the new one to the old one, or copy the data as
appropriate.
