PersistentSet is initialized by criteria query with incomplete data ------------------------------------------------------------------- Key: HHH-7257 URL: https://hibernate.onjira.com/browse/HHH-7257 Project: Hibernate ORM Issue Type: Bug Components: query-criteria Affects Versions: 4.1.2, 3.5.5 Environment: Hibernate 4.1.2 and 3.5.5 java version "1.6.0_31" Java(TM) SE Runtime Environment (build 1.6.0_31-b04) Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode) Ubuntu Linux 11.10 PostgreSQL 9.1, HSQLDB 2.2.8 Reporter: Peter Fodor Attachments: hibernate-criteria-testcase.zip A criteria query with a filter (to the elements of a one-to-many relation) can initialize the persistent set with so that it returns not all items. More detailed description: 1a. A bean is a simple entity 1b. A bean has multiple B beans 2. Query A bean with a filter to B 3a. The returns good result in the terms of A 3b. The set of returned A bean (which contains B instances) does not contains every referenced B item 4. After querying A items again with session.get() the returned A instances neither have the full set (with every B reference) Expected behavior: 1. The Set of A instances should contain every referenced B item. (I know it can not be done with one query in general case) 2. If I query the same items with session.get() it shouldn't be affected by previous query and its set should contain every item. (I think this is the most serious problem) 3. The PersistentSet shouldn't marked with initialized=true, if its content can not be guaranteed that it contains every item. Note: The set of the same query is different (and contains every item), if its PersistentSet is initialized in the same session by an other query. (e.g. with a previous session.get().toString()) For more detailed description please check the test case. -- This message is automatically generated by JIRA.
