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.

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:

[Hibernate-JIRA] Created: (HHH-2052) org.hibernate.pretty.MessageHelper.collectionInfoString tries to cast wrong object to String, causes ClassCastException
by Tree 'Huggy Bear' Hugger (JIRA)
org.hibernate.pretty.MessageHelper.collectionInfoString tries to cast wrong object to String, causes ClassCastException
-----------------------------------------------------------------------------------------------------------------------
Key: HHH-2052
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2052
Project: Hibernate3
Type: Bug
Reporter: Tree 'Huggy Bear' Hugger
Attachments: bugtest.zip
Debug level logging attempted by MessageHelper falls over when constructing a loggable string for a mapped collection on the main entity.
Following the code in the stacktrace, I can see that MessageHelper expects the parent key for the collection relationship to be the primary key, but it is mapped to another field of a different type via a property-ref. Hence the ClassCastException below.
The work around is to set logging to INFO or higher.
I have also attached a pared-down zip with the maven 2 project containing the mappings and the unit test which fails.
The following JIRA issue may be the same thing:
