Emmanuel Bernard commented on EJB-46:
-------------------------------------
Note that I still consider such a usage hacky and is not considered a supported behavior (mainly becasue it highly depend on the Hibernate state discovery mechanism).

[Hibernate-JIRA] Updated: (EJB-46) PrePersist callback method not called if entity's primary key is null
by Emmanuel Bernard (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/EJB-46?page=all ]
Emmanuel Bernard updated EJB-46:
--------------------------------
Summary: PrePersist callback method not called if entity's primary key is null (was: Property Validation should happen after PrePersist/PreUpdate)
Assign To: Emmanuel Bernard
Rename case, since the initial description has been fixed a long time ago and the discussion have slipped.

LocalOnlyContextFactory -- Local server is not initialized
by kal stevens
Could someone help me out with what this might mean?
I am trying to setup an EJB3 project, and I get this.
Caused by: javax.naming.NamingException: Local server is not initialized
at org.jnp.interfaces.LocalOnlyContextFactory.getInitialContext(
LocalOnlyContextFactory.java:45)
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java
:667)

:28)
at org.hibernate.transaction.JTATransactionFactory.configure(
JTATransactionFactory.java:38)
... 27 more
Right now I am running it through intellij.
Is there a prerequisit for setting this up or is it dependent on JBoss or
Seam?
Thanks

[Hibernate-JIRA] Created: (ANN-513) Multiple class validators of the same annotationtype
by Edwin van der Elst (JIRA)
Multiple class validators of the same annotationtype
----------------------------------------------------
Key: ANN-513
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-513
Project: Hibernate Annotations
Type: Improvement
Components: validator
Versions: 3.2.1
Reporter: Edwin van der Elst
Priority: Minor
I have a suggestion for the following problem:
I created an Validator to check if a 'date'> 'another date'
The annotation looks like this:
@After(property="endDate", after="beginDate", message="End should be after begin")
Since it involves 2 properties, it is a class-level validation.
Now....
I want multiple 'after' validations on a single bean.
But that is not possible (you can only place an annotation once on a class).
My proposal is to add an annotation 'Validations':
@Validations( {@After(...), @After(..)} )
I could do the multiple validations in a single validatorclass, but I want all the messages added to the invalidValues array, not a single message.
This change would also require changes in the ClassValidator class.
What do you think of this proposal? Should I add it to Jira (I can propably implement it if there are no objections to the required changes)
