[jboss-user] [EJB 3.0] - Re: RC6-PFD broke mappedBy and GenericGenerator workaround?

[ldebetaz]

Is there a fix or workaround for the "unknown mappedBy" problem?  No matter what I try I get this error.  I have a Party (parent) and a Person (child) that I want to have the same primary key.  The Party needs to control the creation of the primary key value and I want Person to use the same value.  I've tried without the GenericGenerator - just trying to get the code to deploy without even worrying yet about setting the primary key correctly  - and with the GenericGenerator but with no luck.

The code for Party:


  | @Entity
  | public class Party implements Serializable {
  | 
  | 	@Id
  | 	@GeneratedValue(strategy=javax.persistence.GenerationType.AUTO)
  | 	public Long getId() {
  | 		return id;
  | 	}
  | 	
  | 	@OneToOne(optional=true, fetch=javax.persistence.FetchType.LAZY, mappedBy="party", cascade=javax.persistence.CascadeType.ALL)
  | 	public Person getPerson() {
  | 		return person;
  | 	}
  | 	
  | 

Code for Person

  | @Entity
  | public class Person implements Serializable {
  | 	@Id
  | 	@GeneratedValue(generator="foreign")
  | 	@GenericGenerator(name="foreign",strategy="foreign",
  | 			parameters={@Parameter(name="property",value="party")})
  | 	public Long getId() {
  | 		return id;
  | 	
  | 	@OneToOne(fetch=javax.persistence.FetchType.EAGER,cascade=javax.persistence.CascadeType.ALL)
  | 	@PrimaryKeyJoinColumn
  | 	public Party getParty() {
  | 		return party;
  | 	}
  | 

And I get this error

Am I modeling this wrong?  Any help would be greatly appreciated.
