---------------------------------------------------
Key: OPENJPA-1438
URL: https://issues.apache.org/jira/browse/OPENJPA-1438
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.0.0
Reporter: Fay Wang
Assignee: Fay Wang
Fix For: 2.0.0
Given the following entity definitions:
@Entity
@IdClass(PersonId.class)
public class MedicalHistory implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@OneToOne
private Person patient;
private String doctorName;
.....
-------------------------------
@Entity
@IdClass(PersonId.class)
public class Person implements Serializable {
@Id
String firstName;
@Id
String lastName;
String ssn;
...
-------------------------------
public class PersonId implements java.io.Serializable {
String firstName;
String lastName;
-------------------------------
Removing MedicalHistory as shown below throws ClassCastException:
MedicalHistory newMHistory = em.find(MedicalHistory.class, personId);
em.remove(newMHistory);
et.commit();
Caused by: <openjpa-0.0.0-rnull nonfatal general error>
