Revision: 7698
Author: [email protected]
Date: Wed Mar 10 17:23:17 2010
Log: Here's the first ever request with a parameter, and the parameter is
provided by
an object received from a previous RPC call.
The bulk of this is actually two fixes to the mock persistence thingy:
entities
pointing to entities weren't working; and get was returning the canonical
objects, rather than making defensive copies of them.
On to CRUD!
