[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2801) wrong insert/delete order when updating record-set

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: manytomanywithassocclass.tar.gz, manytomanywithassocclassbug.tar.gz, model.zip, test-pro.tar.gz 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... DEBUG - transaction org.hibernate.ejb.TransactionImpl@44ac6a started DEBUG - update timestamp and userstamp for base record set DEBUG - update timestamp and userstamp for base record set DEBUG - update timestamp and userstamp for base record set DEBUG - update timestamp and userstamp for base record set DEBUG - update timestamp and userstamp for base record set DEBUG - select rawtohex(sys_guid()) from dual DEBUG - insert timestamp and userstamp for base record set DEBUG - insert into dseas.PATIENT_SOCIAL_INSURANCE (TIME_CRE, TIME_UPD, USER_CRE, USER_UPD, CODE_MEMBERSHIP_NO, CODE_TYPE_DEFAULT, PATIENT_ID, SOC_INS_ID, ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?)
