| /** |
| * Bug 6119707 - A DATABASE QUERY AND IN-MEMORY QUERY PRODUCES A DIFFERENT RESULT |
| * Test that querying across a 1:1 mapping using a 'simple type' instead of a complex |
| * object in parameters produces an exception. |
| * Needed to support correct query building habits with developers. |
| * e.g. |
| * Incorrect: (where the_parameter = numeric type) |
| * builder.get("owner").equal(builder.getParameter("the_parameter")); |
| * GOOD: (where the_parameter = numeric type) |
| * builder.get("owner").get("id").equal(builder.getParameter("the_parameter")); |
