Hi, I am using MySQL with "MySQL Connector/J 2.0.14" JDBC drivers. In my test the bean property is null both before and after update/flush, but when you load the bean from db using session.load(), the property is "".
Attached to this mail you can find mapping file for my bean, JUnit
test (part of...) that fails and log from this test with "trace" and
"show SQL" set to true.
My JavaBean is generated from that mapping file.
thanks for your support!

GKdvga> What JDBC driver are you using? (I've got a funny feeling it might be
GKdvga> Oracle, which does not differentiate between null and the empty string in
GKdvga> its driver.)
GKdvga> Hibernate doesn't do this. Your code, or possibly your JDBC driver might do
GKdvga> it.
GKdvga> Put a breakpoint in your setter method to discover exactly *where* it gets
GKdvga> set to null and I might be able to give some more guidance....

GKdvga> Hi,
GKdvga> while I was writing tests for my code I ran into one "problem". Now,
GKdvga> I'm not sure if it is a bug or a feature. I am using Hibernate 1.2.3
GKdvga> and MySQL 3.x .
GKdvga> Some of properties in my JavaBean are marked as not null. When I test
GKdvga> the code I set that property to null and try to save() it. The exception
GKdvga> is thrown - as expected. But when I try to do the same and update() the
GKdvga> code the exception is NOT thrown. Value of that property (string) is
GKdvga> set to "" instead. When I use saveOrUpdate(), it works - just like with
GKdvga> save().
GKdvga> Is there something I misunderstand with update()?
GKdvga> I have some test that shows this problem, so if this is not expected
GKdvga> behavior I can send it together with the debug info etc.
GKdvga> thanks in advance!
GKdvga> jaro.
