Revision: 8556
Author: [email protected]
Date: Tue Aug 17 09:57:01 2010
Log: Preliminary implementation of the server-side sync method. When a
record is to
be passed as a parameter, we now pass its uniqueId().
The correct methods on the server are being invoked. However, the
snapshotting
and change detection are not done. So there will be exceptions on the
client.
