hibernate should throw exception differentiating between null and transient
---------------------------------------------------------------------------

                 Key: HHH-4467
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4467
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.2
            Reporter: Dean Hiller


some teams report this as a usabiliy bug, others a feature...you can move to a feature if you like.  

Hibernate should change the exception message 
"not-null property references a null or transient value: net.voicelog.entities.scripts.CompareExpression.expression" 
to be

1. not-null property is referencing a null value
AND
2. not-null property is referencing a transient value

Just do a quick if(property != null) throw 1 else throw 2

I have ran into many users being confused and users should not have to go check if the property is null, hibernate can do a quick check instead and throw 2 different exceptions to make our lives just a little bit easier.  I personally have been tripped up by this a few times myself assuming it was transient or null on accident whereas if it just spit out the right exception to begin with, that would rock for such an easy change!
thanks,
Dean
