[Hibernate-JIRA] Created: (HHH-2116) CLONE -explicit and implicit query with enabled filter gives different results

by Armin Haaf (JIRA)

CLONE -explicit and implicit query with enabled filter gives different results ------------------------------------------------------------------------------ Key: HHH-2116 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2116 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Environment: hibernate 3.2.0.cr2, hibernate annotations 3.2.0.cr1 Reporter: Armin Haaf we are playing around with filters and found a inconsistent behaviour in using a filter in an explicit vs. implicit join. In explicit join a filter is not active, but in an implicit join it is active.

[Hibernate-JIRA] Created: (HHH-2104) Infinite recursion in org.hibernate.cfg.Configuration.setListener(String, Object)

by Daniel Beer (JIRA)

Infinite recursion in org.hibernate.cfg.Configuration.setListener(String, Object) --------------------------------------------------------------------------------- Key: HHH-2104 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2104 Project: Hibernate3 Type: Bug Components: core Versions: 3.1 rc 1 Environment: Hibernate 3.1, but also newer versions contain this bug. Reporter: Daniel Beer When method org.hibernate.cfg.Configuration.setListener(String, Object) is called with second argument set to <null> (in order to remove all listeners of that type) an infinite recursion occurs. Cause: There is a check against null in this method which invokes a wrong method (its a simple typos): if ( listener == null ) { setListener( type, null ); } Instead the method "setListeners(String, Object[])" should be invoked (notice the trailing "s" in the methods name). -- 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-1991) add alias when create a subcriteria

by Jorge L. Middleton (JIRA)

add alias when create a subcriteria ----------------------------------- Key: HHH-1991 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1991 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.1 rc2 Environment: windows Reporter: Jorge L. Middleton Priority: Trivial Its very simple... only I noted this: public DetachedCriteria createCriteria(String associationPath, String alias) throws HibernateException { return new DetachedCriteria( impl, criteria.createCriteria(associationPath) ); } I had a problem with this method because, hibernate doesn't recognize the alias. The point is that you have to use criteria.createCriteria(associationPath, alias); -- 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-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 ?
