[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4584) Query Language needs to support joins on embedded values

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4584?page=c... ] Steve Ebersole commented on HHH-4584: ------------------------------------- Tucked away nice and unassuming like in a little blurb in the section 4.4.5.1 (query language inner joins) is an example which illustrates that one should be able to reference an embedded value (what Hibernate terms a component) as a join path expression terminus. So think something like: "... from Person p join p.name n where name.lastName = ?" where name is a Name component. But the BNF just above implies (arguably) that this should not be possible. It says: {code} join ::= join_spec join_association_path_expression [AS] identification_variable ... join_association_path_expression ::= join_collection_valued_path_expression | join_single_valued_path_expression ... join_single_valued_path_expression::= identification_variable.{single_valued_embeddable_object_field.}*single_valued_object_field {code} Its arguable based on your interpretation of single_valued_object_field. Sadly the spec goes on to no where define the BNF term 'single_valued_object_field' :( -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
