[Hibernate-JIRA] Created: (HHH-3129) Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor

by Jose CHILLAN (JIRA)

Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor ---------------------------------------------------------------------------------- Key: HHH-3129 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3129 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Any Reporter: Jose CHILLAN When the "onCollectionRecreate" is invoked on an Interceptor, the getRole() method returns null. After investigation, the problem is located in the class CollectionEntry in one of its constructors and is easily solved using the patch : public CollectionEntry(CollectionPersister persister, PersistentCollection collection) { // new collections that get found + wrapped // during flush shouldn't be ignored ignore = false; collection.clearDirty(); //a newly wrapped collection is NOT dirty (or we get unnecessary version updates) snapshot = persister.isMutable() ? collection.getSnapshot(persister) : null; // -- ADDED LINE HERE -- role = persister.getRole(); collection.setSnapshot(loadedKey, role, snapshot); } Thanks -- 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-2847) THIS_"."NAME": invalid identifier when using createCriteria with addOrder

by Ashish Tiwari (JIRA)

THIS_"."NAME": invalid identifier when using createCriteria with addOrder ------------------------------------------------------------------------- Key: HHH-2847 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2847 Project: Hibernate3 Issue Type: Bug Components: query-criteria Affects Versions: 3.0.5 Environment: Oracle - 10.2.0 Reporter: Ashish Tiwari We are using hibernate 3.0.5 and once a while I see following error getting generated due to incorrect SQL generated by hibernate: Hibernate: select systembean0_.SYSTEMID as SYSTEMID12_0_, systembean0_.Version as Version12_0_, systembean0_.NAME as NAME12_0_, systembean0_.TYPE as TYPE12_0_, systembean0_.DESCRIPTION as DESCRIPT5_12_0_ from SDSYSTEM systembean0_ order by this_.NAME asc - SQL Error: 904, SQLState: 42000 - ORA-00904: "THIS_"."NAME": invalid identifier This normally works but occasionally we run into the issue mentioned above. I do not see alias "this_" in the sql query and I think that causes the error to happen. Issue is caused by alias not used consistently. In normal case the generated SQL looks like following: Hibernate: select this_.SYSTEMID as SYSTEMID7_0_, this_.Version as Version7_0_, this_.NAME as NAME7_0_, this_.TYPE as TYPE7_0_, this_.DESCRIPTION as DESCRIPT5_7_0_ from SDSYSTEM this_ order by this_.NAME asc I am not sure what causes this problem.

[Hibernate-JIRA] Created: (HHH-6215) final fields can't be set if they're public

by Bogdan Butnaru (JIRA)

final fields can't be set if they're public ------------------------------------------- Key: HHH-6215 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6215 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.4 Environment: Hibernate 3.6.4 Reporter: Bogdan Butnaru As far as I can tell, Hibernate 3.6.4 can set a {{final}} field, _except_ if both the field and the class it belongs to are declared {{public}}. In other words, {noformat} public class Test{ @Column(name = "field") private final String field = null; } {noformat} will work, as will making the class non-{{public}} and the field {{public}}, but {noformat} public class Test{ @Column(name = "field") public final String field = null; } {noformat} will not. The latter causes an {{org.hibernate.PropertyAccessException}} to be thrown when a {{Test}} object is initialized from the database (caused by a {{java.lang.IllegalAccessException}}). (The message I get is _"could not set a field value by reflection setter of one.of.my.Classes.field at org.hibernate.property.DirectPropertyAccessor$DirectSetter.set(DirectPropertyAccessor.java:151)"_) I looked a bit around the sources for 3.6.4 (which I downloaded earlier today) and did a little debugging, and as far as I can tell the problem is in {{DirectPropertyAccessor.getField(Class, String)}}; Specifically, line 176 reads {noformat} if ( !ReflectHelper.isPublic(clazz, field) ) field.setAccessible(true); {noformat} that is, {{setAccessible}} is not called for {{public}} fields even if they are {{final}}. I don't know the code enough to be sure, but I believe the test should check for {{final}} too. There is an identical line in the next method (same name but with two {{Class}} arguments, line 191); I suspect that causes the same problem, but I didn't hit that code in my case (AFAIK because I don't have inherited fields). I'm sorry for not uploading a test case, I don't quite get how to check this, but I hope I pointed close enough to the problem. -- 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-3345) "select new" + "join fetch" = "owner of the fetched association was not present in the select list"

by Anthony Ogier (JIRA)

"select new" + "join fetch" = "owner of the fetched association was not present in the select list" --------------------------------------------------------------------------------------------------- Key: HHH-3345 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3345 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.4.sp1 Reporter: Anthony Ogier I want to create a List<B>, each B containing an entity with "A" type, and I also want for each A to force fetching of its "C" property. public class B { private A a; public B(A a) { this.a = a; } } @Entity public class A { @ManyToOne @JoinColumn private C c; // +get/setter ... } @Entity public class C { @Column private String d; // +get/setter ... // +@OneToMany } Here is the HQL : select new B(a) from A a left join fetch a.c I have that message : org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list When invoking only "from A a left join fetch a.c", all is good and I have ma List<A> with its "C" properties fetched.

[Hibernate-JIRA] Created: (HHH-4897) onFlushDirty not called if only modification was to a collection of elements

by Rob West (JIRA)

onFlushDirty not called if only modification was to a collection of elements ---------------------------------------------------------------------------- Key: HHH-4897 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4897 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2, 3.3.1 Reporter: Rob West Attachments: InterceptorTest.jar We are not seeing onFlushDirty get called if the only modification to a Hibernate-mapped entity is to a collection of elements (e.g. a Set<String> that maps to entries in a related table). It appears that for purposes of calling onFlushDirty, a collection property of an entity can only be considered dirty if that entity is versioned (it may still not be dirty, but it cannot be dirty unless the entity is versioned). For purposes of actually executing SQL, the collection property is properly considered to be dirty based on a call to PersistentCollection.isDirty(), but this prevents an interceptor from acting on the modifications. I've attached a jar file that contains (source) modifications to the InterceptorTest to add an additional test case highlighting this, along with modifications to User.java and User.hbm.xml to add an additional collection of elements property. The assertNotNull on line 66 (the check of last updated) fails for me locally with the latest hibernate source downloaded from hibernate.org, which appears to be 3.3.2. We currently use 3.3.1 in production. My original forum post is at https://forum.hibernate.org/viewtopic.php?f=1&t=1002411, which contains some additional debugging information while I was figuring out what was going on. As a note: I left the priority here the default. This is a pretty serious issue for us though, as one of the key things we do with interceptors is auditing of changes, and this means that sometimes certain properties do not get audited. We haven't been able to identify any straightforward workaround to implement that is not either fairly invasive or leaves us open to introducing other equally or more serious bugs in our code.

[Hibernate-JIRA] Created: (HHH-3848) Hibernate.org documentation is out of date (Should be 3.3.x)

by Adam Brod (JIRA)

Hibernate.org documentation is out of date (Should be 3.3.x) ------------------------------------------------------------ Key: HHH-3848 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3848 Project: Hibernate Core Issue Type: Bug Components: documentation Affects Versions: 3.3.1 Reporter: Adam Brod The Hibernate Core API documentation is out of date. It appears to be from Hibernate 3.2.x. In Hibernate 3.3 most of the cache API was deprecated. Online, there is zero documentation for the new APIs. By downloading the source I can see there is some javadoc.
