I have the following mapping:
<class name="Person" proxy="Person" table="Person_">
<id name="OID" column="OID_" type="Guid">
<generator class="guid.comb"/>
</id>
<version name="Version" column="Version_"/>
<set name="Properties" lazy="true" inverse="true" cascade=
"all-delete-orphan">
<key column="PersonOID_"/>
<one-to-many class="Property"/>
</set>
</class>
And the following class:
public class Person
{
private Iesi.Collections.Generic.ISet<Properties> _properties;
public void AddProperty(Property property)
{
p.Person = this;
_properties.Add(p);
}
public void RemoveProperty(Property property)
{
p.Person = null;
_properties.Remove(p);
}
}
...
public void TransferProperty(Property p, Person thisPerson, Person
otherPerson)
{
//thisPerson.RemoveProperty(property);
otherPerson.AddProperty(property);
}
Calling TransferProperty results in otherPerson's version getting
incremented, but thisPerson's version is unchanged. So when multiple users
try to call TransferProperty at the same time -- no persistence exception
gets thrown.
*What should I do, so that both thisPerson and otherPerson get their
versions incremented by the call to TransferProperty ???*
Thanks,
Peter
P.S. I tried calling RemoveProperty, but that resulted in an exception --
"NHibernate.ObjectDeletedException: deleted object would be re-saved by
cascade (remove deleted object from associations)."
