criteria-api: filtering by key-many-to-one causes invalid sql ------------------------------------------------------------- Key: HHH-1570 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1570 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.1.2 Reporter: Joris Verschoor Attachments: HHH-1570-fix.patch, HHH-1570-it.patch, hibernate.patch We have a class Price that has a composite-id using a couple of key-properties and some key-many-to-ones) One of those is "transportation", which has a many-to-one to transportationType When we query using: criteria.add(Expression.eq("price.transportation.transportationType.id", transId);, we get an invalid SQL statement: The table of transportation was not selected. I will try to make a testcase today or tomorrow, depending on my schedule.. Things will be more clear by then... We have created a work-around, by mapping the transportationID twice: once in key-property, and once as a many-to-one. (instead of one key-many-to-one)
