Re: serialising SimpleORM classes?

Hi

It seems to be related to this issue in the Sun Bug Tracker.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6208166

What happens is this sequence:
ObjectInputStream.readObject()
   .. starts reading SQueryResult
   ...partially constructs my SRecordInstance subclass
   ...starts trying to deserialise the SDataSet field in SRecordInstance
   --> calls LinkedHashMap.readObject
     --> calls LinkedHashMap.putForCreate
       --> calls hashCode() on my partially constructed SRecordInstance subclass
             which throws a NullPointerException

Not sure how to solve this yet.

Regards, Noel.
