[Hibernate-JIRA] Created: (HHH-3151) using property-ref and not-null="true" simultaneously in collection <key> element crashes with ArgumentIllegalException

by boris schukin (JIRA)

using property-ref and not-null="true" simultaneously in collection <key> element crashes with ArgumentIllegalException ----------------------------------------------------------------------------------------------------------------------- Key: HHH-3151 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3151 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: hibernate 3.2.5 Reporter: boris schukin Example: Let's we have one class "MetaMethod" and second class "MetaParameter" . Class MetaMethod has a list of MetaParameters. Corresponding tables are: CREATE TABLE META_METHOD (ID VARCHAR2(50) NOT NULL ,CODE VARCHAR2(40) NOT NULL ,BCN_CODE VARCHAR2(40) NOT NULL ,NAME VARCHAR2(100) ) ALTER TABLE META_METHOD ADD (CONSTRAINT SK_BFN_PK PRIMARY KEY (ID)) ALTER TABLE META_METHOD ADD (CONSTRAINT SK_BFN_UK1 UNIQUE (CODE ,BCN_CODE)) CREATE TABLE META_PARAMETER (ID VARCHAR2(50) NOT NULL ,BFN_CODE VARCHAR2(40) NOT NULL ,BCN_CODE VARCHAR2(40) NOT NULL ,SEQUENCE_NUMBER NUMBER(4,0) NOT NULL ,TYPE VARCHAR2(255) NOT NULL ) ALTER TABLE META_PARAMETER ADD (CONSTRAINT SK_BFA_PK PRIMARY KEY (ID)) ALTER TABLE META_PARAMETER ADD (CONSTRAINT SK_BFA_UK1 UNIQUE (BFN_CODE, BCN_CODE ,SEQUENCE_NUMBER)) ALTER TABLE META_PARAMETER ADD (CONSTRAINT SK_BFA_BFN_FK1 FOREIGN KEY (BFN_CODE ,BCN_CODE) REFERENCES META_METHOD (CODE ,BCN_CODE)) You see, the foreign key (BFN_CODE ,BCN_CODE) on the table META_PARAMETER is organized by native key (CODE ,BCN_CODE) of the META_METHOD table. Structure of classes is simple (in my opinion), so i introduce the hibernate mappings: <class name="com.stinscoman.kernel.api.meta.MetaMethod" table="META_METHOD" > <id name="id" column="ID" length="40" type="long"> <generator class="assigned" /> </id> <properties name="theKey" unique="true"> <property name="code" column="CODE" not-null="true"/> <property name="bc" column="BCN_CODE" not-null="true" /> </properties> <property name="name" column="NAME" /> <list name="parameters" cascade="all-delete-orphan"> <key property-ref="theKey" not-null="true" update="false"> <column name="BFN_CODE" not-null="true"/> <column name="BCN_CODE" not-null="true"/> </key> <list-index column="SEQUENCE_NUMBER" /> <one-to-many class="com.stinscoman.kernel.api.meta.MetaParameter"/> </list> </class> <class name="com.stinscoman.kernel.api.meta.MetaParameter" table="SK_BFN_ARGUMENT"> <id name="id" column="ID" length="40" type="long"> <generator class="assigned"/> </id> </class> Now, somewhere in hibernate session, i try to put a parameter to method MetaMethod method = ... <the code to obtain MetaMethod object> MetaParameter param = ... <the code to obtain MetaParameter object> method.getParameters().add( param ); Ok. When session is flushing i always have: Caused by: org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of com.stinscoman.kernel.api.meta.MetaMethod.code at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:171) at org.hibernate.tuple.component.AbstractComponentTuplizer.getPropertyValue(AbstractComponentTuplizer.java:64) at org.hibernate.tuple.component.AbstractComponentTuplizer.getPropertyValues(AbstractComponentTuplizer.java:70) at org.hibernate.tuple.component.PojoComponentTuplizer.getPropertyValues(PojoComponentTuplizer.java:83) at org.hibernate.type.ComponentType.getPropertyValues(ComponentType.java:353) at org.hibernate.type.ComponentType.getPropertyValues(ComponentType.java:348) at org.hibernate.engine.ForeignKeys$Nullifier.nullifyTransientReferences(ForeignKeys.java:77) at org.hibernate.engine.ForeignKeys$Nullifier.nullifyTransientReferences(ForeignKeys.java:47) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:282) ...

[Hibernate-JIRA] Created: (HHH-3614) Version Tagging

by Corneil du Plessis (JIRA)

Version Tagging --------------- Key: HHH-3614 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3614 Project: Hibernate Core Issue Type: New Feature Components: envers Reporter: Corneil du Plessis I would like to suggest a new feature for version tagging in envers. I have a suggestion for how it can be implemented. @Versioned @Taggable public class MyEntity { @Id private Long id; @Basic String someProp; } By implication results in @RevisionTagEntity which can be seen as public class MyEntity_tag { @RevisionNumber private Integer version_numer; @RevisionTagTimestamp private long tag_date; @RevisionTagValue private String tag; // Other @Colum can apply as well as using Integer or Enum // Other properties allow like with @RevisionEntity } This produces a table like: create table MyEntity_tags ( id bigint not null, version_number integer not null, // version_number is _revision tag_date timestamp not null, // assigned when create or modified version_tag varchar(255) not null, // Could be customizable with RevisionTagEntity similar to RevisionEntity primary key (id, version_tag), ); EntityTagging will be a utility class using EntityManager and Entity or Collection of Entities and do: tagLatestVersion(Object entity, String tag) tagVersion(Object entity, Integer version, String tag) moveTag(Object entity, String targetVersion, String tag) determineVersion(Object entity, String tag) The following could be added to allow the retrieval of versions of collections of entities that are tagged in a specific way. RevisionProperty.tag(String tag) -- 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] Commented: (HHH-663) Enabling filters for get(), load(), ... - please reopen HHH-67

by Markus Merder (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-663?page=co... ] Markus Merder commented on HHH-663: ----------------------------------- I agree to Erico, it's not clear, that filters only work for HQL-Queries. Maybe Filters should be called HQLFilter instead. I have experienced some applications, which could not use filters due to the lack of filtering every statement (also on update, delete). > Enabling filters for get(), load(), ... - please reopen HHH-67 > -------------------------------------------------------------- > > Key: HHH-663 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-663 > Project: Hibernate Core > Issue Type: Improvement > Components: core > Affects Versions: 3.0.5 > Reporter: Michael Wyraz > > Hibernate filters apply only to queries, not to load/get by id. This was also postet as bug HHH-67. This bug was rejected with the reason "This is by intent and thus not a bug." > The Hibernate documentation says for Filters: "Filters can be used like database views, but parameterized inside the application.". The filter is attached to a class or a collection. > So in my oppinion there's no reason _not_ to use filters with get() or load(). In fact, that's what users expect after reading the documentation. > So the current behaviour is a bug. Either in hibernate or in the documentation. > Michael. -- 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-3612) Coarse-Grained Lock

by Xavier Dury (JIRA)

Coarse-Grained Lock ------------------- Key: HHH-3612 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3612 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Xavier Dury Hibernate should allow a cluster of entities to share a single version. An update of any element in the cluster should lock the root element of the cluster. Take the classic example of Order (root) which have many OrderLines. If Order has a version property, each time an OrderLine is added or removed, its version will increase. If Orders must also satisfy an invariant saying that the total amount (= sum for each line of price x quantity < MAX_AUTHORIZED_AMOUNT), two users could concurrently modify (update) two different lines and bypass the invariant. If the Order would have been locked by the first user, the second couldn't have committed his changes. The first user can lock the Order with Session.lock(FORCE) but something more declarative would be better. http://martinfowler.com/eaaCatalog/coarseGrainedLock.html -- 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
