Ray,
It is totally legal to create more than one object with the same id. The
only thing that would prohibit this is the use of a GUID (Globally Unique
ID) generator to create object ids or a unique contraint on the primary
key field in the database schema.
Castor provides the HIGH/LOW key generator with the global=true
attribute. This will generate GUIDs for your objects. Additionally,
other GUID generators can be plugged into Castor via the castor.properties.
Hope this helps.
