Patch for bug HHH-2076 and to be able to use <formula> in <key> for <one-to-many>
---------------------------------------------------------------------------------
Key: HHH-2086
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2086
Project: Hibernate3
Type: Patch
Components: core
Versions: 3.2.0.cr4
Reporter: Xavier Brénuchon
Attachments: formula_one_to_many.patch
Hello,
There is a patch to correct bug HHH-2076 and make an improvement for HHH-944.
In fact, theses 2 cases are linked. They need, amongst other things, a formula in the right part of outer join.
This patch is simple but many class concerns (to propagate formula templates).
About formula in one-to-many :
You must have at least a column (not only formula), because it's not possible to have an Update order without at least a column. If it is the case, hibernate patch will raise an MappingException rightly.
This patch add two TestCase :
org.hibernate.test.onetoone.bidirectionnalformula. OneToOneBidirectionalFormulaTest
org.hibernate.test.onetomany.formula. OneToManyFormulaTest
Would it be possible to integrate this patch into Hibernate 3.2 ?

[Hibernate-JIRA] Created: (HBX-812) Fetching Children of Database _crawls_.

Fetching Children of Database _crawls_.
---------------------------------------
Key: HBX-812
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-812
Project: Hibernate Tools
Type: Bug
Components: reverse-engineer
Versions: 3.2beta8
Environment: MySQL 5.0, Eclipse 3.2, JDK 1.5, Beta8 for Hibernate Tools
Reporter: Syd Poetry
I just updated a bunch of components for Eclipse (mostly related to Visual Editor); added a couple of tables to my database, went to regenerate all the POJO clases .hbm.xml mapping files, and found that anything that queries the database schema runs abysmally slow.
Updated the tools from beta6 to beta8 thinking it might be a conflict with one of the updates that was performed, still very slow (5+ minutes to retrieve a list of tables!). Deleted all my hibernate-related XML files thinking it might be a parsing error, went to generate a new console file, and revenge.xml, found out that any listbox that tried to access the schema appeared to be hanging. It finishes after much hard-drive crunching. I have 2.2 GBs free running windows XP, MEM usage is 856 MB out of 1.5 GB physical memory. Just out of curiousity, is *anyone* else having this slow response for schema detection? I'm wondering if I have to update another component like a driver or something like that.

[Hibernate-JIRA] Created: (HBX-895) Content assist doesn't work when an entity alias is not preceded by whitespace

Content assist doesn't work when an entity alias is not preceded by whitespace
------------------------------------------------------------------------------
Key: HBX-895
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-895
Project: Hibernate Tools
Type: Bug
Versions: 3.2beta8
Reporter: Joseph Marques
In an HQL editor:
If I type - "count(col." - and press ctrl+space, I don't get the content assist for col
If I type - "count( col." - and press ctrl+space, I do
Similarly,
If I type - "select a,b." - and press ctrl+space, I don't get the content assist for b
If I type - "select a, b." - and press ctrl+space, I do
It's pretty clear that the lexing is a little bit too tight here, and that for better usability it should be relaxed. The second case isn't as big a deal as the first (because I don't know a single person that doesn't comma-space delimit the select clause, but I'm thinking that some people that don't realize that they have to put a space in front of it might think that the tools simply can't auto-complete inside functions.

The generated SQL (show_sql=true):
Hibernate: select b_.id, b_.aId as aId1_, b_.cId as cId1_ from B b_ where b_.id=?
Hibernate: insert into C (id) values (?)
Hibernate: insert into A (id) values (?)
Hibernate: insert into B (aId, cId, id) values (?, ?, ?)
Hibernate: select a0_.id as id0_0_ from A a0_ where a0_.id=?
Hibernate: select bs0_.aId as aId1_, bs0_.id as id1_, bs0_.cId as cId1_, bs0_.id as id1_0_, bs0_.aId as aId1_0_, bs0_.cId as cId1_0_ from B bs0_ where bs0_.aId=?
I've been having a confusing problem shown above, whereby A has a Map of Bs indexed using the id from an association with C. This Map is inversely mapped for A and with 'Cascade Delete Orphan'. In the second opened session above, where B is removed from A's Map and thus orphaned, B will not be deleted. I have observed B is only deleted if I either set 'lazy="false"' for A's Map or make an interaction with A's Map in the code (before B's removal) like 'a.getBs().get(cId)'. I suspect the lazy intializer is not initializing correctly in the above scenario.
The above scenario does not happen if A's Map is not inversely mapped but B's many-to-one with A is.
Can somebody shed some light on whether this is me using Hibernate incorrectly or is a bug?

[Hibernate-JIRA] Created: (HHH-2355) CGLIBLazyInitializer can not access a public member if parent class is not public
by Daniel Beland (JIRA)
CGLIBLazyInitializer can not access a public member if parent class is not public
---------------------------------------------------------------------------------
Key: HHH-2355
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2355
Project: Hibernate3
Type: Bug
Versions: 3.2.1
Reporter: Daniel Beland
In hibernate 3.2.1, CGLIBLazyInitializer cannot acces a public method if it has been inherited from a parent class that is not public.
Let's say we have a class A, modifier = default (package) with a public method getName() (and setName(String name)).
Then I create a public class B that extends A.
in my code I can retrieve B from the database:
B b = session.load(B.class, new Integer(1), LockMode.NONE);
I receive b with all the values set correctly (So at this point, Hibernate was able to use the method setName() correctly).
In my code if I then try to use b.getName(), I receive and error:
java.lang.IllegalAccessException-->Class org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer can not access a member of class A with modifiers "public"
But I am not trying to access A.getName(), but B.getName() (which is a public method in a public class).
This was working perfectly with Hibernate 2.1.7c and 3.1.3.
The full information about my problem can be found here: http://forum.hibernate.org/viewtopic.php?t=969453

Can not get N first results of query with DB2 dialect (neither with setMaxResults nor with setFetchSize)

Version du pilote JDBC : 2.1.34
Using dialect: org.hibernate.dialect.DB2Dialect
Reporter: Fred
I can't get the N first records from a select request using the setMaxResults method.
HB generates a request that can not be understood by DB2 (select * from ( select rownumber() over() as rownumber etc.... see first stacktrace below)
Moreover, using setFetchSize does not work (see second stack trace below the first one).
Is there a way to tell HB to append " fetch first 10 rows only" to the query (as a workaround) ? Because my DB2 can understand that one :
select *
from MYTABLE
where numseq = '2'
fetch first 10 rows only
thanks !
Fred
