[Hibernate-JIRA] Created: (HHH-2459) Problem with <parent> for 2+ levels of components
by Kevin Bragh (JIRA)
Problem with <parent> for 2+ levels of components
-------------------------------------------------
Key: HHH-2459
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2459
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.2
Environment: Hibernate 3.2.2, Tested on PostgreSQL and HSQL
Reporter: Kevin Bragh
Attachments: test.zip
I have tested several scenarios similar to the above, and I have searched and posted to the forum with no response.
I have attached the faulty code to the thread.
I have a main class (A) with 3 components recusively included as follows:
A -> B -> C <-> D
In the case above, D has a <parent> property to C.
While loading an instance of A, it seems that D.setC(...) is called with the value of the main class A, and not of parent C.
I don't know if this is a bug, or if parent is not recusively supported.
Any help is appreciated.
Thks, K.
NB: I have tried many different examples (with list and composite-element, etc.) and they all fail with 2+ levels of recursion.

[Hibernate-JIRA] Created: (HSEARCH-183) @IndexedEmbedded(prefix="") should either be forbidden or fixed with duplicate ID fields
by Stephane Epardaud (JIRA)
@IndexedEmbedded(prefix="") should either be forbidden or fixed with duplicate ID fields
----------------------------------------------------------------------------------------
Key: HSEARCH-183
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-183
Project: Hibernate Search
Issue Type: Improvement
Components: mapping
Affects Versions: 3.0.1.GA
Reporter: Stephane Epardaud
If all my entities have their ID property named "id" and they use @IndexedEmbedded(prefix="") then there will be several fields named "id" per document.
This results in very unfortunate behaviour when indexes are updated because this id is then used by HS to remove Lucene documents, so instead of removing only the one document we are updating, HS removes all documents whose ID have been embedded in the index.
We use prefix="" in order to accumulate embedded entities' "text" fields into the root entity so that we can search on any "text" field, embedded or not. This is required because there seems to be no support for a term wildcard such as "*.text:foo" which would search on any term ending by ".text" for the string "foo".
Either prefix="" is supported, and this behaviour should be changed, or at the very least trigger a visible warning, or it is not supported and it should be documented and an exception should be thrown.
Since it is behaviour I need, I favour supporting it, so I've patched DocumentBuilder to store the ID of the root entity in a special field like _hibernate_class, so that when we update the index only the appropriate entity index document is removed. This works well, but has the side-effect of ignoring the name of the ID as specified in @DocumentId.
An alternative would be to still store the root ID is a "special" field, and keep storing the ID under a field name as specified by the user. As long as we only use the "special" ID for index updating all will work well.
I can produce both patches and documentation if you agree (and choose).

[Hibernate-JIRA] Created: (HHH-3220) Patch to prevent "org.hibernate.AssertionFailure: possible non-threadsafe access to the session" error caused by stateless sessions
by Dan Bisalputra (JIRA)
Patch to prevent "org.hibernate.AssertionFailure: possible non-threadsafe access to the session" error caused by stateless sessions
-----------------------------------------------------------------------------------------------------------------------------------
Key: HHH-3220
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3220
Project: Hibernate3
Issue Type: Patch
Components: core
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6, Apache Derby on Mac OSX & PC
Reporter: Dan Bisalputra
Priority: Minor
When performing a query in a stateless session, the query loads objects in a two-phase process in which a temporary persistence context is populated with empty objects in the first phase, then the objects' member data are read from the database in the second phase. If one of the objects contains an association or a collection, it performs a recursive call to the session's get() method. The get() method clears the temporary persistence context, so if the parent object contains any other associations to be read in the second phase, Hibernate throws an assertion because they are not found in the persistence context.
This patch solves the problem by only clearing the persistence context when the recursion ends. It passes all the unit tests for our application, but I have not tested it with any of the Hibernate unit tests.

[Hibernate-JIRA] Created: (HHH-3637) Union in where doesn't works for Sybase, need to evict test case
by Juraci Paixao Krohling (JIRA)
Union in where doesn't works for Sybase, need to evict test case
----------------------------------------------------------------
Key: HHH-3637
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3637
Project: Hibernate Core
Issue Type: Improvement
Components: testsuite
Environment: Sybase ASE 15.0.2
Reporter: Juraci Paixao Krohling
Assignee: Juraci Paixao Krohling
It seems that Sybase doesn't supports UNION inside WHERE clauses, causing the test DynamicFilterTest#testSqlSyntaxOfFiltersWithUnions to fail. The scenario for this test case is not described in the documentation, but I would expect it to work:
http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter....
The query is:
select
category0_.CAT_ID as CAT1_6_,
category0_.name as name6_,
category0_.eff_start_dt as eff3_6_,
category0_.eff_end_dt as eff4_6_
from
CATEGORY category0_
where
'abc' in (
select
d.reg
from
department d
where
(
d.dept_id=123
)
union
select
p.name
from
sales_person p
)
If executed only the queries from inside the where clause (the two selects with union), it works as expected. Also, if removed the union and one of the queries inside the where, it works as expected. So, the problem happens only when using union inside a where clause.
For now, I'd suggest to evict this test for Sybase.
