Is it possible to use Many-To-One association with not-null="false" ???

[b]Hibernate version: 3.0[/b]

Hi, i have folowing mapping accosiation:


<many-to-one name="EventType" lazy="false"
class="ee.regio.tracker.dto.EventType"
column="termevent_type_id"
cascade="none"
not-null="false"/>

I putted not-null="false", cuz i need it. And if i try to store object with null instead of EventType i get:

Is it possible to use not-null=false in my case???

Hello

your class is a alone class or is a subclass??

yes, u can use not-null="false" , inclusive if is a Foreign Key

why you use lazy = "false" ??? , in the xdoclet not appear the lazy attribute

and about this

2006-06-25 19:23:52,703 ERROR [org.jboss.ejb.plugins.LogInterceptor] RuntimeException in method: public abstract java.util.Collection

can u show me the mentionated Collection???? , (i guess that is the other class), i odnt use jboss, not yet :(

good luck

What code did you write to get this error ?

Is '0' being stored in termevent_type_id column instead of 'null' ?

You could also keep hibernate from throwing an exception by using not-found="ignore" in the many-to-one tag. Please understand the implications before you use this.

Which unsaved-value are you using ? Maybe you put 0 instead the classical null and it fucks some others things up ?
