[hibernate-issues] [Hibernate-JIRA] Issue Comment Edited: (HHH-7203) IdentityGenerator fails with JOINED Inheritance when inserting entity to PosgtreSQL

IdentityGenerator fails with JOINED Inheritance when inserting entity to PosgtreSQL ----------------------------------------------------------------------------------- Key: HHH-7203 URL: https://hibernate.onjira.com/browse/HHH-7203 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 3.6.10 Environment: Hibernate 3.6.10, PostgreSQL 9.1-901.jdbc4 Reporter: Andrey Vlasov Attachments: hibernate-postgreSQL-bug-HHH-7203.zip We have inheritance strategy JOIN in table. Now we want to insert some entity inheriting from this one, and we want PostgreSQL to automatically generate the ID for the new entity. Hibernate runs IdentityGenerator.GetGeneratedKeysDelegate.executeAndExtract(), which uses "persister.getIdentifierColumnNames()[0]" as identifierColumnName (in Hibernate 3.6.10 it's line 99 in IdentityGenerator) to getGeneratedIdentity. This identifierColumnName points actually to the child entity identifierColumn. So, this inserting to the parent table fails on getting identifier by wrong column name (a column from the child entity). This issue is a result of HHH-6580 changes.
