[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1794) HQL query (list) that SELECTs instances mixed with scalars returns NULLs (instance mappings are in a one-to-one relation)

HQL query (list) that SELECTs instances mixed with scalars returns NULLs (instance mappings are in a one-to-one relation) -------------------------------------------------------------------------------------------------------------------------- Key: HHH-1794 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1794 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.1.3 Environment: Hibernate 3.1.3 Postgres 8.1.2 Java 1.5.0_06 Reporter: Conor Tee Attachments: hibernate-scalar-problem.tar.gz Given that "a" is a table whose id is reflected in table "b" as a PRIMARY FOREIGN KEY. Mapping a->b and b->a with the appropriate "one-to-one" mappings (I hope), then "select a, b from A a join a.b b" returns "a" and "b" instances correctly.. However: (this is where I see the problem) "select a, b, 'Some scalar' from A a join a.b b" or "select a, a.B, 'Some scalar' from A a" returns "a" and the "scalar" correctly, but returns NULL for b! Attached is a working example with a README, Postgres schema build script and ant "build & run" script
