Fuhwei Lwo commented on TUSCANY-1132:
-------------------------------------
Frank, I think I may have misunderstood the serialization format mentioned in
the 2.1 spec. It seems we do need to serialize the whole tree along with the
path to the target data object. So we did serialize correctly but have a
problem to deserialize it.
> SDO Java serialization/deserialization throws an exception when the
> serialized data object is not the root and its container is of
> AnyTypeDataObject

> With or without the patch of TUSCANY-1131 to fix the problem in
> XMLDocumentImpl.java, this problem always exists. With the fix from
> TUSCANY-1131, now I got this exception. I believe there are still some
> problem in the SDO Java serialization/deserialization code.
