[Hibernate-JIRA] Created: (EJB-273) refresh() throws entity not managed exception

by Charles Canning (JIRA)

refresh() throws entity not managed exception --------------------------------------------- Key: EJB-273 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-273 Project: Hibernate Entity Manager Type: Bug Components: EntityManager Versions: 3.2.1 Reporter: Charles Canning Priority: Critical When you call EntityManager.refresh() to reattach an entity to the entitymanager, it throws: java.lang.IllegalArgumentException: Entity not managed at org.hibernate.ejb.AbstractEntityManagerImpl.refresh(AbstractEntityManagerImpl.java:260) The code is: public void refresh(Object entity) { checkTransactionNeeded(); //adjustFlushMode(); try { if ( ! getSession().contains( entity ) ) { throw new IllegalArgumentException( "Entity not managed" ); } getSession().refresh( entity ); } catch (MappingException e) { throw new IllegalArgumentException( e.getMessage(), e ); } catch (HibernateException he) { throwPersistenceException( he ); } } It is checking if the object is already in the session - this will not allow me to reattach. If I "cast" the EM to the session delegate, refresh works fine because it doesn't contain this check.

[Hibernate-JIRA] Created: (HBX-826) Code generator: sortedset are not instantiated by default

by Julien Fourment (JIRA)

Code generator: sortedset are not instantiated by default ---------------------------------------------------------- Key: HBX-826 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-826 Project: Hibernate Tools Type: Bug Components: hbm2java Versions: 3.1beta3 Environment: Hibernate 3.1.3 and plus. MySQL 5.0 Reporter: Julien Fourment Priority: Minor Hi, When defining a regular (not sorted) set in an hbm file, the generated java will define the field as this: private Set<Package> packages = new HashSet<Package>(0); But when defining a sorted set in the my hbm file (using sort attribute with a comparator class) the generated java looks like this: private SortedSet<ServiceVersion> versions; Type is correct, but the field in not populated with a default implementation by default, like treeset ? I would expect something like : private SortedSet<ServiceVersion> versions = new TreeSet<ServiceVersion>(new myComparator()); -- 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

[Hibernate-JIRA] Created: (HBX-825) hbm2java: Circular dependency between POJO source generation and Comparator class compilation

by Julien Fourment (JIRA)

hbm2java: Circular dependency between POJO source generation and Comparator class compilation --------------------------------------------------------------------------------------------- Key: HBX-825 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-825 Project: Hibernate Tools Type: Bug Components: hbm2java Versions: 3.1beta3 Environment: Hibernate 3.1.3 and +. Using MySQL 5.0 Reporter: Julien Fourment Attachments: example_and_traces.zip Hi, My java objects are generated from the xml files using hbm2java. One of my collection is sorted using a Comparator class. hbm2java fails saying the comparator cannot be instantiated. But as the comparator makes reference to my java object, it cannot be compiled before the generation happened. We have a circular dependency here. (see example enclosed). Is there any way to fix this ?

[Hibernate-JIRA] Created: (HHH-2488) Resolution of filters' conditions should be postponed till all mappings are loaded.

Resolution of filters' conditions should be postponed till all mappings are loaded. ----------------------------------------------------------------------------------- Key: HHH-2488 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2488 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.2 Environment: Hibernate-Version: 3.2.2.ga Java(TM) SE Runtime Environment (build 1.6.0-b105) Reporter: Dmitry Katsubo When trying to use the possibility to define the conditions for the same filters in {{<filter-def>}}, the following exception occurs, as the resolution of conditions should be done at a later stage, after all mappings are loaded: {noformat} Exception in thread "main" java.lang.NullPointerException at org.hibernate.cfg.HbmBinder.parseFilter(HbmBinder.java:2931) at org.hibernate.cfg.HbmBinder.bindCollection(HbmBinder.java:1462) at org.hibernate.cfg.HbmBinder$2.create(HbmBinder.java:2757) {noformat} The example of definition, that uses filters: {code:xml|title=clauses.hbm.xml|borderStyle=solid} <class name="ClauseFolderImpl" table="stc_folders"> <id name="id"> <generator class="native" /> </id> <property name="name" not-null="true" /> <property name="private" not-null="true" /> <set name="subFolders" outer-join="false" cascade="none"> <key column="parentId" /> <one-to-many class="ClauseFolderImpl" /> <filter name="folderFilterLimited" /> <filter name="folderFilter" /> </set> <filter name="folderFilterLimited" /> <filter name="folderFilter" /> </class> <filter-def name="folderFilterLimited" condition="(parentId is null or (languageId = :languageId and procedureTypeId = :procedureTypeId))" > <filter-param name="languageId" type="int" /> <filter-param name="procedureTypeId" type="int" /> </filter-def> <filter-def name="folderFilter" condition="(parentId is null or private = :isPrivate)"> <filter-param name="isPrivate" type="boolean" /> </filter-def> {code} As Hibernate ues DTD to check the validity of configuration file, the {{<filter-def>}} definitions can't be moved to the beginning of the configuration file.

[Hibernate-JIRA] Created: (HHH-2503) AbstractEntityPersister swallows JDBCExceptions in processGeneratedProperties

by Dag Liodden (JIRA)

AbstractEntityPersister swallows JDBCExceptions in processGeneratedProperties ----------------------------------------------------------------------------- Key: HHH-2503 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2503 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1, 3.2.2, 3.2.3 Environment: 3.2.2GA and trunk Reporter: Dag Liodden Seems to be a small typo on line 3718 in AbstractEntityPersister (trunk and 3.2.2 GA) which makes exceptions during property generation being logged but not thrown: catch( SQLException sqle ) { JDBCExceptionHelper.convert( getFactory().getSQLExceptionConverter(), sqle, "unable to select generated column values", selectionSQL ); There should be a throw in there I guess. :) catch( SQLException sqle ) { throw JDBCExceptionHelper.convert( getFactory().getSQLExceptionConverter(), sqle, "unable to select generated column values", selectionSQL ); This bug will not be noticeable in most cases and is probably why it hasn't been detected / fixed so far. The method in question (processGeneratedProperties) is used for retrieving properties that are marked as "generated" in the mapping document / annotations - in other words any value that the database provides and is considered "read-only" from the Hibernate application's point of view. The generated value is retrieved by an extra select statement executed by Hibernate after an entity has been inserterd and / or updated (according to how the generated property is flagged). In my particular case, a property (not a key) is marked as generated="insert", so after Hibernate inserts a new entity to the database, it will immediately do a select and set the generated property to the value the database returns. Only in rare cases will this select fail in any way - in fact, I cannot think of any situations other than mapping errors (e.g getInt on a CHAR column) that can cause errors in this last select. That is in addition to my situation - a deadlock. My entity class uses uuid.hex generator for the PK, but at one point, we introduced a second unique key due to purely aestethic reasons. This is a SQL Server identity column. Since we don't do any explicit table locking during the inserts, we end up with deadlocks every time the following happens: T1: INSERT INTO TABLE (ID) values (?) T2: INSERT INTO TABLE (ID) values (?) T2: SELECT GENERATED_ID FROM TABLE WHERE ID = ? -- T1's insert hasn't been committed, so what should the the generated ID be? Deadlock! T1: SELECT GENERATED_ID FROM TABLE WHERE ID = ? ... SQL Server throws an error to indicate the deadlock, but due to the missing throw in the processGeneratedProperties-method, it is never shown to the process doing the insert. The generated property is not set and retains it's null (or 0 in case of a primitive) without the business logic ever knowing that the entity could not be saved. -- 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

[Hibernate-JIRA] Created: (HHH-2320) Regression: optional properties under a <join> tag no longer update properly

by Chris Jones (JIRA)

Regression: optional properties under a <join> tag no longer update properly ---------------------------------------------------------------------------- Key: HHH-2320 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2320 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1, 3.2.0.cr4, 3.2.0.ga, 3.2.0.cr5 Environment: hibernate 3.2.0.cr4 through 3.2.1.ga hsql 1.8.0.7 and Oracle 9i Reporter: Chris Jones This was specifically introduced with the revision 10217 changes on the 3.2 branch in src/org/hibernate/persister/entity/AbstractEntityPersister.java Given the following setup: <class name="Thing"> <id .../> <join table="JOIN_TABLE" optional="true"> <key column="THING_ID" not-null="true"/> <property name="joinedProperty" column="JOINED_PROPERTY"/> </join> </class> scenario: Thing thing1 = new Thing(); thing1.setJoinedProperty("thing1"); save(thing1); // a record in the JOIN_TABLE is created properly and updates on the property can occur Thing thing2 = new Thing(); thing2.setJoinedProperty(null); save(thing2); // no record in JOIN_TABLE is created thing2.setJoinedProperty("thing2"); save(thing2); // in revision 10216, hibernate correctly runs an INSERT to create a JOIN_TABLE record with the value "thing2" // in revision 10217, hibernate incorrectly runs an UPDATE to try and update a non-existant record in the JOIN_TABLE with the thing2 id It looks like the expectation.verifyOutcome() method should be throwing a StaleStateException if the attempted update effects 0 rows. I will try and get an official hibernate testcase going and possibly a patch, but I wanted to enter this now in case there is something I'm missing that makes this change in functionality intentional. -- 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
