> 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.
