Russ,

exactly how are you using the generator? The easy way that works is to use
GeneratorLinks and have a check in your before insert trigger so that it
only creates a new value if none is supplied. Relying only on your insert
trigger will get you into lots of trouble and your client application will
lose track of all newly inserted data, making it impossible for you to
modify or delete them until you reopen your query.
