[Hibernate-JIRA] Created: (HHH-2342) support <load-collection> for stored procedures (see 3.2 documentation section 16.2.2)

by Rick Bradshaw (JIRA)

support <load-collection> for stored procedures (see 3.2 documentation section 16.2.2) -------------------------------------------------------------------------------------- Key: HHH-2342 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2342 Project: Hibernate3 Type: New Feature Components: core Environment: Any new hibernate version/update - Oracle is my personal DBMS preference Reporter: Rick Bradshaw In the 3.2 documentation 16.2.2 "Using Stored Procedures for Querying" it specifies that "<load-collection>" is not supported. The ability to load collections from stored procedures is a powerful idea. I have done it manually within my own Java implementation and it is a big time / headache saver. Many of the DB models I work with (and don't have control of) are full of inconsistencies that can be re-modeled and disguised within a stored procedure that returns sys_refcursor. Adding the <load-collection> feature will make it really easy/fast to map into hibernate the result sets of stored procedures. -- 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-2757) Cascade.cascadeCollectionElements ClastCastException for non-entity element types

by Alan Krueger (JIRA)

Cascade.cascadeCollectionElements ClastCastException for non-entity element types --------------------------------------------------------------------------------- Key: HHH-2757 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2757 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.2 Environment: Hibernate 3.2.2.ga with PostgreSQL 8.2 Reporter: Alan Krueger When trying to flush changes in EntityMode.DOM4J, a composite element causes a ClassCastException in Cascade.cascadeCollectionElements when invoked by Cascade.cascadeCollection. The latter allows the call to the former when the element is of ComponentType, but assumes in the former always casts to EntityType if EntityMode.DOM4J is in effect.

[Hibernate-JIRA] Created: (HHH-2756) PostLoadEventListener is triggered on not fully loaded entity

by Roman Pichlík (JIRA)

PostLoadEventListener is triggered on not fully loaded entity ------------------------------------------------------------- Key: HHH-2756 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2756 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1 Reporter: Roman Pichlík Priority: Minor PostLoadEventListener is triggered, but entity is not fully loaded especially is not possible to operate on mapped collection because org.hibernate.LazyInitializationException: illegal access to loading collection is thrown. PostLoadEventListener should be triggered when is entity fully loaded. Let say, we have Parent, Child entity and PostLoadEventListener which iterates over child collection. public class Parent { private Set<Child> children; } public class PostLoadEventListener implements PostLoadEventListener { public void onPostLoad(PostLoadEvent event) { Parent parent = (Parent) event.getEntity(); for(Child child: parent.getChildren()){ // org.hibernate.LazyInitializationException: illegal access to loading collection System.out.println(child); } } } Fix tip: see org.hibernate.loader.Loader#initializeEntitiesAndCollections, if i understood well the key are following statements. if ( hydratedObjects!=null ) { int hydratedObjectsSize = hydratedObjects.size(); if ( log.isTraceEnabled() ) { log.trace( "total objects hydrated: " + hydratedObjectsSize ); } for ( int i = 0; i < hydratedObjectsSize; i++ ) { TwoPhaseLoad.initializeEntity( hydratedObjects.get(i), readOnly, session, pre, post ); //event is trigerred here } } //but collection are loaded by this code if ( collectionPersisters != null ) { for ( int i=0; i<collectionPersisters.length; i++ ) { if ( !collectionPersisters[i].isArray() ) { endCollectionLoad( resultSetId, session, collectionPersisters[i] ); } } } //post event handlers should be trigerred here -- 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-2754) Inner classes in methods cannot be used in select clause when with conjunction with "typesafe Java object" mechanism

by Adam Wozniak (JIRA)

Inner classes in methods cannot be used in select clause when with conjunction with "typesafe Java object" mechanism -------------------------------------------------------------------------------------------------------------------- Key: HHH-2754 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2754 Project: Hibernate3 Issue Type: New Feature Affects Versions: 3.2.4.sp1 Reporter: Adam Wozniak Hello Here in the documentation to Hibernate Core: http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#queryhql-s... ... we have a following example: select new Family(mother, mate, offspr) from DomesticCat as mother join mother.mate as mate left join mother.kittens as offspr But this mechanism doesn't work when Family class is defined as inner class in a method. So when I wrote something like this: void myBusinessMethod() { class Family3 { private String rowid; private long coId; private int csSeqno; public Family3() { // } @SuppressWarnings("unused") public Family3( final String rowid , final long coId , final int csSeqno ) { //System.out.println("ssss"); this.rowid = rowid; this.coId = coId; this.csSeqno = csSeqno; } } ... and within this method I'm trying to do this: query = sess.createQuery( "select new typesafe_Java_object.TypesafeJavaObjectEMRWTest$1Family3(t.id, t.coId, t.csSeqno) from BSCSCgTaroptLog t"); list = query.list(); ... then I'm slapped by a following exception: org.hibernate.hql.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [typesafe_Java_object.TypesafeJavaObjectEMRWTest$1Family3] [select new typesafe_Java_object.TypesafeJavaObjectEMRWTest$1Family3(t.id, t.coId, t.csSeqno) from pl.capgemini.tme.bonobo.model.BSCSCgTaroptLog t] at org.hibernate.hql.ast.QuerySyntaxException.convert(QuerySyntaxException.java:31) at org.hibernate.hql.ast.QuerySyntaxException.convert(QuerySyntaxException.java:24) (...) So the question is: Is it possible to add another method to org.hibernate.Session: public Query createQuery(String queryString, FactoryType factoryToGenerateMyInnerEntities) ??? Why do I need such mechanism? I rewriting a legacy system (Oracle PL/SQL) and I have many different HQL queries. To use "typesafe Java object" I must make my mediate classes static. But then I would have a kind of class bloat. And this is the reason why I would like to hide those classes and make them much more locally (for example inside my one single java method). Kind regards, Adam Wozniak -- 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: (HSEARCH-90) negative List capacity in FullTextQueryImpl.list()

by Sheldon Shi (JIRA)

negative List capacity in FullTextQueryImpl.list() -------------------------------------------------- Key: HSEARCH-90 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-90 Project: Hibernate Search Issue Type: Bug Components: query Affects Versions: 3.0.0.beta3 Reporter: Sheldon Shi Priority: Minor I did this query: fullTextQuery.setFirstResult(sr.getOffset()); fullTextQuery.setMaxResults(sr.getLength()); List results = fullTextQuery.list(); sr.getOffset() and sr.getLength() are pagination parameters. They happened to be carried from another query as a session properties (not the right thing to do here but it happened). In my case offset was 10 and length was 10. The new search result is empty, so these lines of code in FullTextQueryImpl gave a negative capacity for list exception: int first = first(); int max = max( first, hits ); Session sess = (Session) this.session; List<EntityInfo> infos = new ArrayList<EntityInfo>( max - first + 1); because max=-1 and first=10. Would it be nice if a check is done before assign List capacities? -- 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
