Serialization errors

Hello,

I'm getting errors trying to deserialize some SimpleORM objects. (using
serialization is necessary due to the the way I am integrating SimpleORM
with Wicket)

It seems that SRecordMeta uses readResolve() to treat itself as a
singleton, but I don't think that you can do this if the object graph
that you're serializing contains the record meta (such as if you're
serializing a SFieldMeta), because of the wording here:
http://java.sun.com/j2se/1.3/docs/guide/serialization/spec/input.doc6.html
(the "Note" section in particular).

The error I'm getting is:
java.lang.NullPointerException

at simpleorm.dataset.SRecordMeta.getField(SRecordMeta.java:246)

at simpleorm.dataset.SFieldMeta.readResolve(SFieldMeta.java:186)

at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

at
sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)

at java.lang.reflect.Method.invoke(Method.java:585)

at
java.io.ObjectStreamClass.invokeReadResolve(ObjectStreamClass.java:1033)

at
java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1728)

...etc

Any help is appreciated,

Thanks,
