| /** |
| * This test added for bug 2766379: Expression.doesConform not unwrapping as |
| * it traverses object relationships. |
| * <p><b>Test description:</b> |
| * <ul> |
| * <li>A wrapping policy is used on Employee, and conforming is enabled. |
| * <li>A query with expression emp.anyOf("managedEmployees").get("firstName").equal("Marcus") is called. |
| * <li>The registered result then has its valueholders triggered, so that conform |
| * result on the second query can work. |
| * <li>The query is then repeated. When the anyOf is traversed in doesConform, |
| * the resulting collection should be correctly unwrapped, allowing the |
| * second doesConform and the test to suceed. |
| * </ul> |
