Hardy Ferentschik updated METAGEN-76:
-------------------------------------

    Summary: hashCode is treated as a persistent attribute  (was: SingularAttribute generated for hashCode method in @Embeddable)

> hashCode is treated as a persistent attribute

>             Project: Hibernate Metamodel Generator
>          Issue Type: Bug
>          Components: processor
>    Affects Versions: 1.1.1.Final
>         Environment: hibernate-jpamodelgen 1.1.1.Final, postgresql 8
>            Reporter: Hrotkó Gábor
>            Assignee: Hardy Ferentschik

> I got a class composite id class for a table with @Embeddable.
> It has two properties, and the equals and the hashCode methods.
> When hibernate-jpamodelgen 1.1.1.Final generates the metaclasses, I got a SingularAttribute with the name "hashCode" generated. But hashCode is not a property in the entity.
