Oracle sequences for id generation
I am trying to increase performance by switching from id brokers to
Oracle sequences. I've changed my schema file to use the native id
method alla:
<database
name="segadb01"
defaultIdMethod="native"
Yet, at runtime, when I attempt to store a new record, I get this error:
org.apache.torque.TorqueException: IdGenerator for table 'users' is null
After looking through my generated classes and the Torque source code,
I'm convinced that the addIdGenerator() method of the
org.apache.torque.map.DatabaseMap class is never being called with the
native IDMethod as an argument. Thus, when BasePeer tries to get the
IdGenerator for my class, it gets a null instead, since only IDBroker's
are available for ID generation (I've confirmed this by adding some
debugging lines to the Torque source).
My question is: What instructs Torque to initialize the idGenerators
collection in the DatabaseMap class (via addIdGenerator())? Is this
something dynamic, based on which adapter you're using? Should
something in the schema file be determining this? Do I need to do it
manually? Is it a bug?
I'm using Torque 3.0. Any help would be appreciated.
