[jboss-jira] [JBoss JIRA] Updated: (HIBERNATE-59) @OneToMany collection is not filled when it should when the PK is of uniqueidentifier

[Tobias Bergman (JIRA)]

     [ http://jira.jboss.com/jira/browse/HIBERNATE-59?page=all ]

Tobias Bergman updated HIBERNATE-59:
------------------------------------

    Description: 
I have found a problem when using uniqueidentifier as PK and FK.
A collection which should have entires are empty. The same code will have a non-empty collections when tested on glassfish.


import javax.persistence.*;
import java.util.List;

@Entity
@Table(name = "A")
public class A
{
	@Id
	@Column(name = "Id")
	private String mId;

	@OneToMany(mappedBy = "mA")
	private List<B> mBList;

	//Getter and setters to the members...
}

@Entity
@Table(name = "B")
public class B
{
	@Id
	@Column(name = "Id")
	private String mId;

	@ManyToOne
	@JoinColumn(name = "AId")
	private A mA;

	//Getter and setters to the members...
}

When the db type is an uniqueidentifier the mBList list is not filled! If the db type is changed to a string the List is filled correctly.
But it works with uniqueidentifier when the entity is merged (when creating a new entity A and some B's).
