Hello,
This is somewhat related to my earlier post (IPersistable interface with
a myid property that could get implemented by all entities in the model)
I tried to dig a little more and here is my "second" question reloaded:
1. Could I use the strategy property of the GenericGenerator to indicate
the use of a custom IdentifierGenerator ?
2. Could this custom IdentifierGenerator extend the TableHiLoGenerator?
3. Is there any way I could inject the name of the entity being
persisted into this custom TableHiLoGenerator? Note that the adnotation
will be made on the IPersistable interface.
Please see my earlier post for the spadcore.ecore attachment.
Thanks a lot for your patience
Liviu
