Hello,

I read in the GWT docs that some support has been added to the RPC
implementation to support enhanced JDO/JPA classes. See "Serializing
Enhanced Classes" in
http://code.google.com/intl/hu-HU/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideSerializableTypes.

My question is: does it really work with the JDO/JPA implementation of
AppEngine (or better: with DataNucleus in general)?

For example if I send a complex graph of detached entities to the
client, I modify some deeply nested properties in the graph, then I
send them back to the server, will it really handle the modifications
as expected? (Eg. it will only update the changed entities in the DB.)

Thanks for your help!
Regards:
Norbi
