wrong insert/delete order when updating record-set
--------------------------------------------------
Key: HHH-2801
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2801
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.4.sp1
Environment: hibernate-3.2.4.sp1, hibernate-annotations-3.3.0.GA, hibernate-entitymanager-3.3.1.GA, Oracle 10g Express Edition
Reporter: Christoph Mayerhofer
Attachments: model.zip
Overview: I have a record with a OneToMany association. From this associated record-set a record is removed and added again, both records identified with the same key. When doing a merge, I get a Unique constraint violation, because Hibernate first tries to insert the new record. Hibernate should first delete the old record, and after this insert the new record, avoiding the unique constraint violation.
Detailed description: I have the following entities: Patient, SocialInsurance, PatientSocialInsurance. A patient could have several social insurances assigned to it. A social insurance could be assigned several times to a patient, we have a m:n relation between Patient and SocialInsurance. The relation-table has the name PatientSocialInsurance, with a unique constraint over patient_id and social_insurance_id. Each POJO inherits from a Base-POJO, which holds the id and the insert- and update-timestamps and userstamps.
Base ---> PatientEntity ---> Patient
Base ---> SocialInsuranceEntity ---> SocialInsurance
Base ---> PatientSocialInsuranceEntity ---> PatientSocialInsurance
Note: All *Entity model objects are generated with Hibernate-Tools from the db-schema, assuming that there are no wrong annotations, no wrong fields or wrong getter-/setter-methods in these model-classes.
(I have enclosed all model-classes within an zipped attachment.)
Now I try to delete an existing social insurance from a patient and add the same social insurance to the patient again:
public void deleteSocialInsurance(Patient p, PatientSocialInsurance s) {
if (p == null || s == null) {
throw new IllegalArgumentException();
}
s.setSocialInsurance(null);
s.setPatient(null);
p.getPatientSocialInsurances().remove(s);
}
public void addPatientSocialInsurance(Patient p, PatientSocialInsurance s)
throws DuplicatePatientSocInsException {
if (p == null || s == null) {
throw new IllegalArgumentException();
}
s.setPatient(p);
p.getPatientSocialInsurances().add(s);
}
After doing a merge on the patient object, I get the following error:
DEBUG - persisting patient...
