> 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)
