EntityManager.find returns an object without its id

[idan <id...@gmail.com>]

Hi,

I would like to find an object and then call EntityManager.remove for
removing it from the persistency context.
When i call find and specify the desired object's id i receive an object but
its id (the field i annotated with @Id) has a null value and therefore when
calling remove afterwards the JDBC query created behind the scenes looks for
a null value instead of the id i originally specified.

When debugging openjpa i found somewhere that there's some configuration for
copying identity fields or something....

Help!

Thanks,
Idan

My code:

		_em.getTransaction().begin();
		SimplePerson p = (SimplePerson) _em.find(SimplePerson.class, 100);
		_em.remove(p);
		_em.getTransaction().commit();

My class looks like this:
@Entity
@Table(name = "SimplePerson")
public class SimplePerson {

	@Id
	private Integer id;
	@Basic
	private String name;
	@Basic
	private String address;
	@Basic
	private String email;
		
	public SimplePerson(Integer id) {
		this(id, "SimplePerson #" + id, "SimplePerson # " + id + " Address",
"SimplePerson" + id + "@temp.com");
	}
	
	public SimplePerson(Integer id, String name, String address, String email)
{
		this.id = id;
		this.name = name;
		this.address = address;
		this.email = email;
	}

	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}

After hours of looking around i found this:
http://openjpa.208410.n2.nabble.com/Entity-data-missing-in-enhanced-mode-td4938207.html

The problem is with OpenJPA's Eclipse Enhancer.
I switched to one of the alternatives and everything works fine.
