[Hibernate-JIRA] Created: (HHH-2787) Criteria Aggregate Projections do not JOIN additional tables on which restrictions apply

by Sami Dalouche (JIRA)

Criteria Aggregate Projections do not JOIN additional tables on which restrictions apply ---------------------------------------------------------------------------------------- Key: HHH-2787 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2787 Project: Hibernate3 Issue Type: Bug Components: query-criteria Affects Versions: 3.2.5 Environment: PostgreSQL Dialect Reporter: Sami Dalouche Priority: Critical Hi, When you have a Criteria Object, on which you : - Add Aggregate Projections such as rowCount() - createAlias("whatever").add(Restrictions.*..) It looks like that the "whatever" table is NOT joined, even though it is joined OK when the projections are not there. So, here is an approximate Unit test that should throw an exception (I couldn't create a complete test case since I couldn't get the unit tests to run on my machine -any link explaining this step somewhere ?): Criteria c1 = s.createCriteria(Enrolment.class) .setProjection( Projections.projectionList().add(Projections.rowCount(), "rowCount") ); Criteria studentCriteria = c1.createAlias("student", "st"); studentCriteria.add(Restrictions.eq("name", "whatevername")); It should complain saying the "st.name" alias does not exist, because the student class has not been joined.

[Hibernate-JIRA] Created: (HBX-900) Support ctrl+shift+t in the Hibernate Console perspective

by Joseph Marques (JIRA)

Support ctrl+shift+t in the Hibernate Console perspective --------------------------------------------------------- Key: HBX-900 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-900 Project: Hibernate Tools Type: Bug Versions: 3.2beta8 Reporter: Joseph Marques In other perspectives, ctrl+shift+t will pop open a dialog that allows me to select some type (some class on the source path). I find myself wanting to work in the Hibernate perspective more often, but I'm hindered by the fact that I can't easily open new types with this shortcut. I took a look at "preferences > general > keys" but I didn't see anything that should prevent the shortcut from working in the Hibernate perspective. Oddly, ctrl+shift+r works in the perspective, and it seems to be set up nearly identically in the keyboard shortcuts. Is there something that I'm missing? -- 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: (ANN-527) reference a target entity (in a collection) by entity name

by Armin Haaf (JIRA)

reference a target entity (in a collection) by entity name ---------------------------------------------------------- Key: ANN-527 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-527 Project: Hibernate Annotations Type: New Feature Components: binder Reporter: Armin Haaf It is only possible to reference a targetEntity by class. @ManyToMany(targetEntity = TestImpl.class) List<Test> myList; This makes it impossible to exchange TestImpl.class implemention by another implemention by the mappings definition. It would be helpful to reference a targetEntity by name. @ManyToMany(targetEntityName = "Test") This would help a lot to implement moduls and frameworks. Another way to support this would be to search for a implementation of the collection elements (which are typically Interfaces) in the mapped entities -- 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-2546) fetch="select" doesn't work when there are no mapped columns in joined except <key

by Derar Bakr (JIRA)

fetch="select" doesn't work when there are no mapped columns in joined except <key ---------------------------------------------------------------------------------- Key: HHH-2546 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2546 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3 Environment: Windows XP Pro Reporter: Derar Bakr java.lang.StringIndexOutOfBoundsException: String index out of range: -2 at java.lang.String.substring(String.java:1768) at java.lang.String.substring(String.java:1735) at org.hibernate.persister.entity.AbstractEntityPersister.renderSelect(AbstractEntityPersister.java:2899) at org.hibernate.persister.entity.SingleTableEntityPersister.generateSequentialSelect(SingleTableEntityPersister.java:647) at org.hibernate.persister.entity.SingleTableEntityPersister.postInstantiate(SingleTableEntityPersister.java:696) .... Everything is very simple. There is stupid code in SelectFragment class, method toFragmentString, line 94. String that is being created there, contains list of fields, like a "f1, f2, f3, ..., fn". ", " is being added in every iteration, without check for it is first iteration. And in class AbstractEntityPersister., method renderSelect, line 2899, where that method is called, this first ", " is deleted using substring(2). So no check for empty string. I suggest to add check :))) I just create dynamic mappings programmatically, so create empty join subclass mappings - and in created table there are no fields by default except foreing key. -- 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
