Hi Nick,
I'll take the test home and try to execute it later.

Ok, got it to fail using a very simply test case. Attached the patch
to the current test case as well as the extra object I created. If you
run it you should get the following exception:
org.exolab.castor.jdo.PersistenceException: Requested to load/fetch an
object of type jdo.test1158.ExtendedObject, where persistent storage
returned an object of type class jdo.test1158.BaseObject
The problem is that it sees the parent of DependentObj as being loaded
because BaseObject is loaded. And when it goes to try and load the
ExtendedObject it just gets all confused. Not sure what the design for
this is, but it looks like you are loading BaseObject seperatly first,
then, if you find an extended object if you find a class that extends
BaseObject with the same ID and replacing it? Not sure one this one.
