I've have the following hbm file:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Proj.Core" namespace="Proj.Core.Entity">
<class name="Unit" table="Unit" select-before-update="false" >
<id name="Id" column="UniId" type="Int16" unsaved-value="-1">
<generator class="identity"/>
</id>
<timestamp name="UpdatedUtc" column="UniUpdatedUtc"
generated="always"/>
<property name="Enabled" column="UniEnabled" type="Boolean"
not-null="true"/>
<property name="Name" column="UniName" type="String" not-
null="true" length="30"/>
<property name="Factor" column="UniFactor" type="Double" not-
null="true"/>
</class>
</hibernate-mapping>
I implemented my project base on Gustavo Ringel's article "uNHAddIns
Persistent Conversation" at
http://gustavoringel.blogspot.com/2009/02/unhaddins-persistence-conversation-part_08.html
When I try to save a new Unit object/entity with Id = -1, I get an
StaleObjectStateException with text: "Row was updated or deleted by
another transaction (or unsaved-value mapping was incorrect):
[Proj.Core.Entity.Unit#-1]". The object is saved using
Session.SaveOrUpdate.
What is wrong with my definition or what do I have to define
differently, so NHibernate recognizes new objects/entities itself, so
I don't have to do it myself an use Session.Save for a new object?
