Right, after a couple of breakpoints and a little bit of backtracking
I have a working version of this.
I've added 2 new methods recreate-instance-using-class and recreate-instance.
This is used by get-cached-instance and %deserialize which bypasses
initialize-instance
and calls appropriate methods for the persistent and persistent-object classes.
Please find the attached patch.
cheers,
