Vladimir V commented on HHH-3824:
---------------------------------

hibernate distribution 3.6.0.Final
Issue still here.
Ignores "referencedColumnName" and always try`s to fetch using primary key;

@Entity
@DiscriminatorValue("3")
//@Table InformingLinks 
public class InformingLink_z extends InformingLink {}

@Entity
public class Informing {
    @OneToOne(cascade = CascadeType.ALL,fetch = FetchType.EAGER)
    @JoinColumn(name="n",referencedColumnName = "n1")
    InformingLink_z informingLink;
}

createQuery("from Informing o left outer join fetch o.informingLink")
generates
"select * from Informing i left outer join InformingLinks il on i.n=il.n" must be "=il.n1 and DiscriminatorValue=3"

same error for 
createQuery("from Informing")

> When i try to join 2 entities by OneToOne using a Non-primary key column,  it throws the following exception:
> org.hibernate.PropertyAccessException: could not get a field value by reflection getter of com.xxx.domain.Inventory.sku
> Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field com.inwk.estore.server.domain.Inventory.sku to java.lang.Integer
> [Full stacktrace attached]
> sku is the Non-primary key String join column by which im trying to do a OneToOne join between Item and Inventory entity.
> Apparently its trying to interpret Sku as an Integer column. Adding columnDefinition as VARCHAR/String doesn't help either
> Mappings for Item and Inventory are below:
> class Item{
> @Id
> Long id;
> @Column
> String sku;
> //some more properties
> @OneToOne(optional = true)
> @JoinColumn(name = "sku", referencedColumnName = "sku", insertable = false, updatable = false)
> Inventory inventory;
> }
> class Inventory{
> @Id
> Long id
> @Column
> String sku
> @Column
> Long quantity;
> }
