> While i was debugging I saw a method
> public IdentityTransform getPrimaryKeyTransform(Entity entity) in the class IdentityDefinerBuilder. Here based on size of pkFields the SimplePKTransform or CompoundPKTransform class is selected.
> In the case of a custom class with 1 field also the SimplePKTransform is selected.
> Is this how it should behave? Could you give a general idea of how the primary key values are taken from the Custom classes in OpenEJB?
> Thanks
