Error: Dali not correctly validating @EmbeddedId ID classes [message #671905]

Hello,

I have the following entity and ID class:

@Entity
@Table(name = "Groups")
@Name(value = "group")
public class Group implements Serializable
{
	@EmbeddedId
	private GroupId embeddedId;

	...
}

@Embeddable
public class GroupId implements Serializable
{
	@Column(name = "round_id")
	private Integer roundId;

	@Column(name = "ordinal_nbr")
	private Integer ordinalNbr = 1;

	...
}

The Group class has two columns, both being PK columns. Nothing special really. However, Dali shows an error

"Class GroupId is mapped, but is not included in any persistence unit"

I know I should use the quick fix to include the ID class in persistence.xml, but AFAIK ID classes don't belong there.

This should be a bug, also because using @IdClass mappings instead of @EmbeddedId works in Dali without problems. This error only occurrs with @EmbeddedId mappings.

The problem here seems to be the @Embeddable on the ID class. Removing it removes the Dali error. However, it's not correct to remove the @Embeddable. See here to confirm my mappings should be correct: http://en.wikibooks.org/wiki/Java_Persistence/Identity_and_Sequencing#Embedded_Id

So, is this a bug?
