When using Criteria.setResultTransformer(CriteriaSpecification.ALIAS_TO_ENTITY_MAP) method aliases need to be optional
----------------------------------------------------------------------------------------------------------------------
Key: HHH-2965
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2965
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.2
Environment: 3.2.2 Oracle 10G
Reporter: Ittai Zeidman
Priority: Critical
now when using the CriteriaSpecification- ALIAS_TO_ENTITY_MAP the convertion to map is using the aliases array, if it does not find an alias for the property it is not included in the map. I think that if no alias is defined then the propertyName attribute needs to be assigned as the key for the value in the hashmap.
I came across this issue as i have many mapped entities in my system and when using projections i need to use the resultTransformer. this is critical as when using aliases it is duplicated not only to the select clause but to the where clause only which is another open bug (#HB-1331). If one bug is closed then the other can be considered as minor as i can give aliases to every property i need if it does not affect my where clause.

Project: Hibernate Core
Issue Type: Bug
Components: core

Nullability.checkNullability throws PropertyValueException (not-null property references a null property) for a property that ForeignKeys.Nullifier.nullifyTransientReferences just nulled.
I've included an Eclipse Java project which can reproduce the problem (didn't include the jars).
The problem requires a pretty big graph to be reproduce able. The file "Domain Model.jpg" displays the Classes that take part in the problem.
The Domain Model is a simplification of the entities from our application.
In the example, ModelTest.java, there's only one active instance entity of each type (from A to H).
With the given test case, when an instance of a is passed to entityManager.persist(..), then the following exception is thrown:

As noted in TestModel.java, if some of the other entities (namely c, g or h) are passed to persist(), then the problem doesn't occur.
I've tried to debug the problem and the only difference I've seen inside ForeignKeys.Nullifier.nullifyTransientReferences() is that, in the cases where an exception is thrown, then the B instance that C.b points to has the state SAVING, whereas when the exception isn't thrown, then it has state MANAGED.
When the B instance has state SAVING, then ForeignKeys.Nullifier.nullifyTransientReferences() nulls then entry in it's value array.
After that, Nullability.checkNullability(), performs a null check, which fails because ForeignKeys.Nullifier.nullifyTransientReferences() just nulled the property in the values array.
Could it be a solution to reverse the order of the ForeignKeys.Nullifier.nullifyTransientReferences() and Nullability.checkNullability() (See AbstractEventListener.performSaveOrReplicate(...))
or does ForeignKeys.Nullifier.nullifyTransientReferences() instead have to take nullability into considerations?

[Hibernate-JIRA] Created: (HHH-3414) fetch profiles
by Steve Ebersole (JIRA)
fetch profiles
--------------
Key: HHH-3414
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414
Project: Hibernate3
Issue Type: New Feature
Components: core, metamodel
Reporter: Steve Ebersole
Assignee: Steve Ebersole
Fix For: 3.4
The concept of fetch profiles as we are discussing here is basically to allow users to dynamically affect the mapped fetching strategy for associations at runtime.
Consider the following example:
<class name="Person">
...
<set name="addresses" lazy="true" fetch="subselect" ...>
...
</set>
</class>
<class name="Address">
...
</class>
This follows the normal recommendation to map associations as lazy and use a dynamic fetching strategy (ala HQL/Criteria) to modify this lazy behavior at runtime.
The fetaure discussed here would allow the same behavior for loading as well:
<hibernate-mapping>
<fetch-profile name="person-details">
<fetch path="Person.addresses" style="join"/>
</fetch-profile>
</hibernate-mapping>
Or:
<hibernate-mapping>
<class name="Person">
...
<fetch-profile name="person-details">
<fetch path="addresses" style="join"/>
</fetch-profile>
<set name="addresses" lazy="true" fetch="subselect" ...>
...
</set>
</class>
</hibernate-mapping>
Now, doing:
session.enableFetchProfile( "person-details" ).get( Person.class, 1 )...
will load Person#1 as well as their addresses in a single joined query.

Hello,
I have found something that is a bit strange. For @ManyToOne association properties in an @Embeddable class the cascade PERSIST, SAVE-UPDATE option is not working well (not sure for the other cascade types), if the entities associated with ManyToOne are transient. I have created a unit test to check it and I have it attached to this issue. It is a maven2 project, and needs Oracle to run it. If I save the associated entites, then everything works fine, also the data structure is created well.
I have checked the forums and found similar problems, maybe they can help more then my post:
