--------------------------------------

If I have no vonlunteer, not anytime soon.
What I envision is a way to mix @JoinColumn and @Formula for assoications, if anyone interested to contribute let me know

>          Key: ANN-210
>          URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-210
>      Project: Hibernate Annotations
>         Type: Bug

>   Components: binder
>     Versions: 3.1beta7
>  Environment: Hibernate 3.1,  PostgreSQL 8.1.1

> This type of mapping fails:
> @ManyToOne 
> @Formula(value="( select v_pipe_offerprice.offerprice_fk from v_pipe_offerprice where v_pipe_offerprice.id = id )") 
> public OfferPrice getOfferPrice() { return offerPrice; } 
> While the following mapping works as expected:
> <class name="Pipe" table="t_pipe"> 
>  ... 
>     <many-to-one name="offerPrice" 
>                  class="pipetracker.model.price.OfferPrice" 
>                  formula="( select v_pipe_offerprice.offerprice_fk 
>                               from v_pipe_offerprice 
>                               where v_pipe_offerprice.id = id )"/> 
> ... 
> </class>
> This is not being treated as a formula because the generated SQL included a referece to the field pipe.offerprice_id which does not exsist because this is a virtual column calculated from a view.
