OneToMany (parent-child) with composite PK fails when inserting a child.
------------------------------------------------------------------------

                 Key: EJBTHREE-793
                 URL: http://jira.jboss.com/jira/browse/EJBTHREE-793
             Project: EJB 3.0
          Issue Type: Bug
         Environment: Linux
            Reporter: Gunnar Grim


OneToMany (parent-child) with composite PK on the child side fails when inserting a child. Only the first part of the PK has a value. Before em.persist, both key attributes have values but JBoss attempts to insert null into the second key attribute.

The application works fine on Sun Java Application Server 9.0 but fails on JBoss 4.0.5-GA.

The (stripped down) entity beans:

@Entity
@Table(name = "RelMain")
public class RelMain
	implements Serializable
{
	private Long itsMainID;
	private String itsMainText;
	private Set<RelSub> itsSubs;

	public RelMain(Long pMainID)
	{
		itsMainID = pMainID;
	}

	@Id
	@Column(name = "MainID", nullable = false)
	public Long getMainID()
	{
		return itsMainID;
	}

	public void setMainID(Long pMainID)
	{
		itsMainID = pMainID;
	}

	@Column(name = "MainText")
	public String getMainText()
	{
		return itsMainText;
	}

	public void setMainText(String pMainText)
	{
		itsMainText = pMainText;
	}

	@OneToMany(mappedBy="main", cascade={CascadeType.REMOVE})
	public Set<RelSub> getSubs()
	{
	    return itsSubs;
	}

	public void setSubs(Set<RelSub> pSubs)
	{
	    itsSubs = pSubs;
	}
}

@Entity
@Table(name = "RelSub")
public class RelSub
	implements Serializable
{
	private Long itsMainID;
	private String itsSubNo;
	private int itsSubValue;
	private RelMain itsMain;
	
	public RelSub(Long pMainID, String pSubNo)
	{
		itsMainID = pMainID;
		itsSubNo = pSubNo;
	}
	
	@Id
	@Column(name = "MainID", nullable = false)
	public Long getMainID()
	{
		return itsMainID;
	}

	public void setMainID(Long pMainID)
	{
		itsMainID = pMainID;
	}

	@Id
	@Column(name = "SubNo", nullable = false)
	public String getSubNo()
	{
		return itsSubNo;
	}

	public void setSubNo(String pSubNo)
	{
		itsSubNo = pSubNo;
	}

	@Column(name = "SubValue")
	public int getSubValue()
	{
		return itsSubValue;
	}

	public void setSubValue(int pSubValue)
	{
		itsSubValue = pSubValue;
	}
	
	@ManyToOne
	@JoinColumns({
		@JoinColumn(name="MainID", insertable=false, updatable=false)
	})
	public RelMain getMain()
	{
	    return itsMain;
	}

	public void setMain(RelMain pMain)
	{
	    itsMain = pMain;
	}
}
